Getting Ready for Leather Sewing
Before you start sewing leather, you need to get the right things ready. Sewing leather is different from sewing fabric. Leather is strong and does not stretch or move in the same way fabric does. This means you need special needles, thread, and machine parts to do the job well.
Picking the Right Machine
The sewing machine for leather needs to be strong enough to push a needle through a tough material. Not every sewing machine can do this.
Home Sewing Machines
Some home sewing machines can sew leather, but usually only thin or soft types. If you have a standard home machine, check its power. Look for machines that can handle thick fabrics like denim or canvas. These machines often have stronger motors and metal parts inside. They might be able to sew thin to medium-weight leather (about 2-3 ounces). Trying to sew thick leather on a light home machine can break needles, jam the machine, or even damage it for good. So, be careful what kind of leather you choose if you use a domestic sewing machine leather.
Stronger Machines
For thicker leather or sewing leather often, a stronger machine is best.
- Heavy-Duty Home Machines: Some home machines are made to be heavy-duty. They have more power than standard machines. They can often sew medium to slightly thicker leather (up to 4-5 ounces). These are a good step up from a basic home machine.
- Industrial Sewing Machines: These machines are made for sewing tough materials all day long. An industrial sewing machine leather machine is very strong. It can sew thick layers of leather with ease. They have powerful motors and parts built for hard work. If you plan to sew lots of leather or very thick leather (like for bags, belts, or shoes), an industrial machine is the best choice. These are sometimes called a thick leather sewing machine. They cost more and take up more space, but they are built for the job.
When picking a sewing machine for leather, think about the kind of leather you want to sew most often.
Picking the Right Needle
This is one of the most important parts. You cannot use a regular fabric needle to sew leather. Leather needs a special needle. These are called leather sewing needles.
Leather needles are different because they have a special tip. Most fabric needles have a round tip that pushes through the fabric threads. Leather needles have a sharp, triangle-shaped or wedge-shaped tip. This tip cuts a small hole in the leather as it goes through. This makes it much easier for the thread to pass through.
-
Types of Leather Needles:
- Leather Point (or Chisel Point): This is the most common type for lockstitch machines. It cuts a clean slit.
- Triangle Point: Cuts a triangle shape. Works well for thick, stiff leather.
- Diamond Point: Cuts a diamond shape. Makes bold, saddle-like stitches. Good for very heavy leather.
- Spear Point: A sharp, round point. Used for very fine leather where you don’t want a visible cut.
-
Needle Size: Leather needles come in different sizes, just like fabric needles. You need to pick the right size for the thickness of your leather and the thread you use.
- Use larger needles for thicker leather and thicker thread.
- Use smaller needles for thinner leather and thinner thread.
- Sizes often range from 90/14 up to 180/24 or even bigger for industrial machines. Start with a middle size like 100/16 or 110/18 for medium leather and adjust as needed.
Always use a new leather needle for each leather project. Leather dulls needles fast because it is tough. A dull needle will struggle to cut through the leather, skip stitches, break thread, and can even damage your machine. Keep extra leather sewing needles on hand.
Picking the Right Thread
Regular cotton or polyester thread used for fabric is usually too weak for sewing leather. Leather projects need a strong thread that will not break easily and can hold up to wear and tear. This is why you need leather sewing thread.
-
Best Thread Types:
- Nylon Thread: Very strong, resists stretching, and holds up well against rubbing. It is a popular choice for bags, wallets, and straps.
- Polyester Thread: Also strong and resists UV light and water better than nylon. Good for outdoor gear or items that might get wet.
- Bonded Nylon or Polyester: These threads have a special coating that makes them smoother. This helps them pass through leather layers easily without getting caught or fuzzy. This is often the best choice for machine sewing leather.
- Specialty Threads: Some people use thicker decorative threads, but make sure your machine and needle can handle them.
-
Thread Size: Leather sewing thread comes in different sizes or weights. Like needles, choose the thread size based on the leather thickness and the look you want.
- Thicker thread makes stitches that stand out more.
- Thinner thread makes stitches that are less noticeable.
- Common sizes are T70, T90, T135, T210 for medium to heavy leather. Check your machine’s instructions to see what thread sizes it can handle. Home machines usually handle thinner threads (like T70 or T90 maximum). Industrial machines handle much thicker threads.
Using the right thread size for your needle and machine is important. If the thread is too thick for the needle, it can break, skip stitches, or jam the machine. If it is too thin, the stitches might not be strong enough or look good on the leather.
Picking the Right Foot
The presser foot on your sewing machine holds the material down as you sew. Standard metal presser feet can be a problem with leather. Leather does not slide easily like fabric. A metal foot can stick to the leather surface. This makes it hard for the machine to feed the leather through evenly, leading to crooked stitches or the machine getting stuck. This is why you might need a special machine foot for leather.
- Good Feet for Leather:
- Walking Foot: This foot is great for leather. It has its own set of “feed dogs” (the little teeth under the foot) on top. The top feed dogs work with the machine’s feed dogs under the leather to grip both the top and bottom layers at the same time. This helps move the leather evenly, preventing it from sticking or bunching up. This is often the best choice for home machines sewing leather.
- Roller Foot: This foot has small rollers instead of a flat bottom. The rollers let the leather roll smoothly under the foot as you sew. This helps the leather feed through without sticking.
- Teflon Foot (Non-Stick Foot): This foot has a special smooth bottom coating, often Teflon. The non-stick surface helps the foot slide over the leather easily. These are often white or clear. They work well for many types of leather, especially those with a finished or smooth surface.
- Open Toe Foot: While not specifically for leather feed, an open toe foot has a wide opening in front. This gives you a better view of the needle and the stitch line, which can be helpful when sewing tricky materials like leather.
Check what kind of machine foot for leather is available for your sewing machine model. A walking foot or a Teflon foot are highly recommended for making sewing leather easier and getting better results.
Getting Your Leather Ready
Once you have your machine and tools ready, you need to get your leather prepared for sewing. This involves picking the right leather, cutting it, and marking your sewing lines.
Finding the Right Leather
There are many types of leather for sewing. The best kind depends on what you are making and what machine you have.
- Thickness (Weight): Leather thickness is measured in ounces (oz) or millimeters (mm).
- Thin leather (1-3 oz / 0.4-1.2 mm): Good for lining, small items, or clothing details. Can sometimes be sewn on home machines.
- Medium leather (3-5 oz / 1.2-2.0 mm): Common for bags, wallets, journals. Needs a strong home machine or industrial machine.
- Thick leather (5-8 oz / 2.0-3.2 mm): Used for belts, straps, heavier bags. Needs a heavy-duty home machine or industrial machine.
- Very thick leather (8+ oz / 3.2+ mm): Used for saddles, heavy belts, shoe soles. Almost always needs a special thick leather sewing machine (industrial).
- Tannage: How the leather was treated.
- Chrome Tanned: Softer, more flexible, often colorful. Used for garments, bags. Easier to sew than vegetable-tanned.
- Vegetable Tanned: Stiffer, holds shape well, good for tooling or stamping. Used for belts, wallets, saddles. Can be harder to sew, especially when thick.
- Finish: The surface treatment.
- Smooth, finished surfaces are easier to slide under the foot (especially with a Teflon foot).
- Suede or rough-out leather can be harder to feed smoothly. A walking foot is very helpful here.
For beginners, start with thin to medium, softer leather like a 3-4 oz chrome-tanned leather. This will be much easier to work with than thick, stiff vegetable-tanned leather. Think about the types of leather for sewing you want to use most and make sure your machine can handle it.
Simple Ways to Cut Leather
Cutting leather needs to be done well. A clean cut makes sewing easier and looks better.
- Tools:
- Sharp Craft Knife or Utility Knife: Best for straight lines. Use a fresh, sharp blade.
- Rotary Cutter: Good for straight or slightly curved lines, especially on thinner leather. Needs a self-healing mat.
- Heavy-Duty Scissors: Can work for curves or thinner leather, but can be tiring and hard to make smooth cuts on thick leather. Get sharp, leather-specific scissors if possible.
- Cutting Steps:
- Place the leather on a cutting mat (self-healing mat is best).
- Use a heavy ruler or straight edge for straight cuts. Metal rulers are good because you won’t cut into them.
- Hold the ruler firmly.
- Use a sharp knife or rotary cutter. Make several passes with light to medium pressure instead of one hard pass. This gives a cleaner cut and is safer.
- Keep the blade straight up and down.
Cutting leather needs a sharp tool. A dull tool will tear or chew the leather, making it hard to sew neatly.
Simple Ways to Mark Leather
You need to mark where you will sew. But you cannot use pins like you do with fabric because pins leave holes in leather that don’t go away.
-
Tools:
- Silver or Gel Pen: These pens can write on dark leather. Test on a scrap first to make sure it can be removed or hidden.
- Tailor’s Chalk: Can work on some leather surfaces, but might rub off easily.
- Scratch Awl or Compass Point: A sharp metal tool to lightly scratch a line into the leather surface. Only use this where the line will be hidden by stitching or overlapping layers.
- Edge Creaser: A tool that makes a pressed line parallel to the edge. This is a nice way to mark a stitching line that looks professional.
- Temporary Leather Marking Pens: Some companies make pens specifically for marking leather that disappear over time or can be wiped off. Always test on a scrap.
-
Marking Tips:
- Mark on the back (flesh side) of the leather if you can.
- Keep marks light so they don’t show.
- Use tools that won’t damage the leather.
- Mark just before sewing, as some marks can fade or rub off.
Setting Up Your Machine
Once your leather is ready, you need to set up your sewing machine for leather correctly. The stitch length and thread tension are key.
Setting Stitch Length
When sewing leather, you should use a longer stitch length than you would for fabric.
- Why Longer Stitches? Leather gets permanent holes from the needle. If the stitches are too short, the holes are very close together. This can make the leather weak along the stitch line. It can even cause the leather to tear between the stitches.
- Recommended Length: A good starting point is a stitch length of 3mm (about 8-9 stitches per inch) or longer. For thicker leather, you might use 4mm or even 5mm stitch length.
- Testing: Always test your stitch length on a scrap piece of the same leather you are using for your project. See how it looks and if the leather seems strong along the stitch line. Adjust as needed.
Most home machines have a dial or button to change stitch length. Industrial machines also have ways to set this. Make sure you know how to set the stitch length on your sewing machine for leather.
Setting Thread Pull
Getting the right sewing machine tension for leather is very important. Tension is how tight the upper thread and bobbin thread are pulled.
- What Tension Does: The upper thread comes from the spool on top of the machine. It goes through tension discs. The bobbin thread comes from the bobbin underneath. The tension settings control how much pull is on each thread.
- Perfect Stitch: For a perfect stitch, the place where the upper thread and bobbin thread meet should be exactly in the middle of the leather layers.
-
Problems with Wrong Tension:
- Upper Tension Too Tight: The upper thread will pull the bobbin thread up to the top surface of the leather. The stitches will look bumpy on top and flat on the bottom.
- Bobbin Tension Too Tight: The bobbin thread will pull the upper thread down to the bottom surface. The stitches will look flat on top and bumpy on the bottom.
- Tension Too Loose (both): The stitches will look loopy on the back of the leather. They won’t be strong.
-
How to Set Tension:
- Start with the standard tension setting on your machine (often around 4 or 5 on a dial).
- Thread your machine with your chosen leather sewing thread and leather sewing needles. Put your leather piece under the foot.
- Sew a test line on a scrap piece of the same leather.
- Look at the stitches on both the top and bottom of the leather.
- If the stitch is not perfect (meeting in the middle), adjust the upper tension dial. Turn it to a higher number to make the upper thread tighter. Turn it to a lower number to make it looser.
- Sew another test line after each small adjustment. Keep adjusting until the stitches look the same on both sides, with the knot hidden inside the leather.
- Sometimes, you might need to adjust the bobbin tension, but it’s best to try adjusting only the upper tension first. Adjusting bobbin tension is more tricky.
Setting the sewing machine tension for leather might take a few tries. It can change depending on the leather thickness, thread type, and needle size. Always test and adjust before sewing your real project.
Easy Sewing Steps
Now that everything is ready, let’s talk about the actual sewing leather techniques. Sewing leather is different from sewing fabric in how it moves and how you handle it.
How to Start and Stop
Starting and stopping stitches needs care with leather.
- Starting: Lower the needle into the very first spot you want to start sewing. Then lower the presser foot. Hold the thread tails lightly behind the foot for the first few stitches to prevent them from getting pulled under. Start sewing slowly.
- Stopping: When you reach the end of your sewing line, do NOT use the backstitch feature on your machine like you would with fabric. Backstitching in the same holes on leather can weaken the stitch line and make it look messy.
- Securing Stitches: To secure the stitches, sew forward 2-3 stitches. Then, lift the presser foot (leave the needle in the leather). Turn your leather piece around. Lower the foot and sew backward exactly over the last 2-3 stitches you just made. Lift the foot, turn the leather back to the right way, and sew forward again from where you stopped. This locks the stitches neatly on the top. Some people prefer to leave long thread tails and tie them off by hand on the back.
Sewing Straight Lines
Sewing straight lines on leather can be a bit tricky because it doesn’t slide easily.
- Guidance: Use a marked line on the leather or use a seam guide attachment on your machine. You can also put masking tape on your machine bed as a guide.
- Feeding: Let the machine feed the leather. Don’t push or pull the leather. Just gently guide it along your marked line or guide. Pushing or pulling can break needles, mess up stitches, or damage the machine’s feeding system.
- Speed: Sew slowly and evenly. This gives you better control and results in neater stitches. Fast sewing on leather is harder and more likely to cause problems.
Turning Corners
When you need to turn a corner, stop with the needle exactly in the leather at the corner point.
- Stop sewing when the needle is down in the leather at the corner.
- Lift the presser foot.
- Turn the leather carefully with the needle still acting as a pivot point. Turn it until your next sewing line is lined up correctly.
- Lower the presser foot.
- Start sewing again in the new direction.
This method makes a clean, sharp corner stitch.
Making Seams
Joining pieces of leather together (making seams) can be done in different ways.
- Butt Joint: The edges of two pieces meet side-by-side. You might sew a piece of fabric or thin leather on the back to hold them together, or just stitch close to the edge on both pieces.
- Overlap Seam: One edge of leather overlaps another. This is common for straps or when joining panels. Stitch through both layers.
- Edge Stitching: Sewing a line of stitches close to a finished edge. This is often for decoration or to flatten an edge.
- Folded Edge: The edge is folded over once or twice before sewing. This makes a clean, strong edge. Common on bag tops or wallet edges.
When making seams, make sure the edges are lined up well. You can use leather glue or double-sided tape made for leather to hold pieces in place before sewing. This is better than pins.
Handling Thicker Spots
Sewing over areas with multiple layers, like where straps meet a bag body, can be very thick. This is where a thick leather sewing machine or a heavy-duty home machine is needed.
- Go Slow: When you come to a thick spot, slow down the machine even more.
- Hand Crank: If your machine has a handwheel (the big wheel on the side), you can turn it by hand slowly to help the needle go through the thickest parts. Always turn it towards you (the way it normally goes).
- Check Height: Make sure your presser foot can lift high enough to get the thick layers under it. Some machines have a higher presser foot lift feature.
- Leveling Tool: Sometimes, lifting the back of the foot slightly when sewing over a bump helps keep the foot level and feed smoothly. Some special feet or tools can help with this.
If your machine struggles badly with thick spots, it might not be strong enough for that leather. Trying to force it can break parts.
Tips for Making Leather Projects Well
Here are some extra tips for sewing leather:
- Practice: Always practice on scrap pieces of the same leather before sewing your project. Test needles, thread, tension, and stitch length.
- Use Clips: Instead of pins, use binder clips, Wonder Clips, or special leather clamps to hold pieces together before sewing.
- Glue: Use a little bit of contact cement or leather glue to hold seams or layers in place before stitching. Let the glue dry partly before sewing. This helps keep everything from shifting.
- No Going Back: Remember that needle holes are permanent. Once you sew a line, you can’t easily remove it without leaving visible holes. Plan your stitching carefully.
- Use the Right Side: Most sewing happens from the “good” side (grain side) of the leather so you can see your marks or guides.
- Clean Often: Sewing leather creates fine dust and tiny leather bits. Clean your machine regularly, especially around the needle plate and bobbin area, to keep it running smoothly.
- Leather Care: Think about how you will finish the edges (edge paint, burnishing) and care for the finished project (leather conditioner).
These sewing leather techniques and tips will help you get better results.
Fixing Little Problems
Even with the right tools and setup, you might run into some issues when sewing leather. Here’s how to fix common ones:
- Skipped Stitches:
- Reason: Needle is wrong type, wrong size, dull, bent, or inserted wrong. Tension is off. Thread is wrong size or type.
- Fix: Make sure you are using a sharp, new leather sewing needles of the right size. Check it is inserted correctly (flat side usually goes to the back). Check your sewing machine tension for leather. Make sure your leather sewing thread is right for the needle and machine.
- Thread Breaking:
- Reason: Thread tension is too high. Needle is dull, bent, or too small for the thread. Machine is trying to sew layers that are too thick. Thread is low quality.
- Fix: Lower the upper tension. Use a larger, new leather sewing needles. Check if your sewing machine for leather can handle the leather thickness. Use good quality leather sewing thread. Slow down when sewing thick spots.
- Machine Not Feeding Leather:
- Reason: Presser foot is sticking to the leather. Stitch length is too short. Feed dogs are not set right (check manual).
- Fix: Use a walking foot, roller foot, or Teflon machine foot for leather. Increase the stitch length. Check that the feed dogs are not lowered (they should be up to grip the leather).
- Uneven Stitches:
- Reason: Tension is wrong. Leather is not feeding smoothly. You are pushing or pulling the leather.
- Fix: Adjust sewing machine tension for leather. Use a walking foot or Teflon foot. Guide the leather gently; do not push or pull. Sew at a slow, steady speed.
Most problems come down to using the wrong needle or thread, wrong tension, or trying to sew leather that is too thick for the machine.
Keeping Your Leather Project Nice
After you finish sewing, taking care of your leather project will help it last a long time.
- Finishing Edges: Raw leather edges can shed or look unfinished. You can:
- Leave them raw (can work for some styles and leather types).
- Burnish them (rub them smooth, often with a tool and water or special liquid).
- Apply edge paint (a special paint that seals and colors the edge).
- Cleaning: Clean leather gently. Use a damp cloth for dust or dirt. Avoid harsh chemicals.
- Conditioning: Over time, leather can dry out. Use a good leather conditioner to keep it soft and prevent cracks. Apply it with a soft cloth, let it soak in, and buff off any extra.
- Storage: Keep leather items out of direct sunlight for long periods, as this can fade the color. Store them in a breathable dust bag, not plastic.
Proper care is the final step in making beautiful, lasting leather goods with your sewing machine for leather.
Common Questions About Sewing Leather (FAQ)
Q: What stitch length should I use for sewing leather?
A: Use a longer stitch length than for fabric. Start with 3mm (about 8-9 stitches per inch) and go up to 4mm or 5mm for thicker leather. Shorter stitches can weaken the leather.
Q: Can I sew thick leather on a regular home sewing machine?
A: Generally, no. Regular domestic sewing machine leather capacity is limited. They can usually handle thin to medium leather (2-3 oz). Thicker leather (4oz+) needs a heavy-duty home machine or a thick leather sewing machine (industrial machine). Trying to sew leather that is too thick can damage your machine.
Q: Do I really need special leather sewing needles?
A: Yes! Leather sewing needles have a special cutting tip that goes through leather properly. Using a regular fabric needle will be very difficult, can skip stitches, break thread, and damage the leather or machine. Always use a new, sharp leather needle.
Q: What kind of thread should I use for sewing leather?
A: Use strong leather sewing thread like bonded nylon or bonded polyester. Regular cotton or garment polyester thread is not strong enough for leather. Pick a thread size that matches your needle size and the thickness of your leather.
Q: What is the best machine foot for sewing leather?
A: A walking foot is highly recommended as it helps feed the top and bottom layers evenly. A Teflon foot or roller foot are also good options because they slide over the leather surface without sticking. Look for a proper machine foot for leather.
Q: How do I set the sewing machine tension for leather?
A: Set your sewing machine tension for leather so the stitches look the same on the top and bottom of the leather, with the knot hidden inside the layers. Test on a scrap first and adjust the upper tension dial as needed.
Q: How do I hold leather pieces together for sewing without using pins?
A: Use clips like binder clips, Wonder Clips, or leather clamps. You can also use double-sided tape made for fabric/leather or a small amount of contact cement or leather glue along the seam line to hold layers before stitching.
Q: What should I do if my machine is skipping stitches when sewing leather?
A: The most common reasons are a dull or wrong type of needle, incorrect tension, or the wrong thread. Make sure you are using a sharp, new leather sewing needles, check your sewing machine tension for leather, and ensure your leather sewing thread is the right size and type.
Q: Can I backstitch at the start and end of seams on leather?
A: It’s best not to backstitch like you do on fabric, as it puts too many holes in the same spot and weakens the leather. Instead, sew forward a few stitches, turn the leather, sew backward over those stitches to lock them, then turn back and continue sewing forward.
Conclusion
Sewing leather with a sewing machine is a skill you can learn. It takes the right tools and a little practice. By choosing the right sewing machine for leather, using special leather sewing needles and leather sewing thread, picking the right machine foot for leather, and setting the sewing machine tension for leather correctly, you can sew many types of leather for sewing. Remember the key sewing leather techniques like using a longer stitch length and not pulling the leather. Start with simpler projects and thinner leather, and as you get better, you can work up to using a thick leather sewing machine for more complex items. Don’t be afraid to try! Getting your leather ready, setting up your machine with care, and sewing slowly will lead to great results. Soon, you will be making your own leather goods.
