Preparing Your Shirt for Hemming
Before you can start machine sewing hem lines, proper preparation is key to a smooth and accurate outcome. This stage involves getting your shirt ready, gathering your tools, and setting up your workspace.
Gathering Your Supplies
Having all your materials at hand will prevent interruptions and ensure a more enjoyable sewing experience. Here’s what you’ll need:
- The Shirt: The item you wish to hem. Make sure it’s clean and pressed.
- Sewing Machine: Ensure it’s in good working order and you’ve threaded it correctly. This is one of the most crucial sewing machine basics.
- Matching Thread: Choose a thread color that closely matches your shirt fabric.
- Fabric Scissors: Sharp scissors are essential for a clean cut.
- Measuring Tape or Ruler: For accurate measurement of the hem depth.
- Fabric Marker or Chalk: To mark your hemline.
- Pins: To hold the hem in place while you sew.
- Iron and Ironing Board: For pressing seams and the hem. This is vital for crisp finishes.
- Seam Ripper (Optional): In case you need to undo any stitches.
- An All-Purpose Presser Foot: This is the standard foot that comes with most sewing machines.
Washing and Ironing Your Shirt
It’s always a good idea to pre-wash your garment before hemming. Fabrics can shrink or change slightly after washing, and you want to make sure your hem is done to the final size.
- Wash and Dry: Follow the care instructions on your shirt’s label.
- Iron: Once dry, press the shirt thoroughly. Pay special attention to the area where you plan to create the hem. A smooth surface makes marking and sewing much easier.
Measuring and Marking the New Hemline
Accurate measurement is the foundation of a good hem.
- Try On the Shirt: Put the shirt on and determine the desired length. You can ask a friend to help mark the length with pins, or you can use a mirror.
- Measure the Current Hem: If you’re shortening a shirt, first measure how much you need to cut off from the existing hem.
- Mark the Cut Line: Using your measuring tape and fabric marker or chalk, draw a line where you want to cut. Remember to account for the hem allowance. A common hem allowance is 1 inch (2.5 cm) or 1.5 inches (3.8 cm). This is the extra fabric you’ll fold up.
- Mark the Fold Lines: After cutting, you’ll need to mark where to fold the fabric.
- First fold: Mark along the line where the original hem was.
- Second fold: Mark another line parallel to the first fold, at your desired hem depth. This creates a clean, double-folded hem.
Cutting Off Excess Fabric
Once you’ve marked your cut line, it’s time to remove the excess fabric.
- Lay the Shirt Flat: Ensure the fabric is smooth and not stretched.
- Cut Carefully: Using sharp fabric scissors, cut along your marked line. Try to make this cut as straight and even as possible. For thicker fabrics, a rotary cutter and mat can offer more precision.
Mastering Hemming Techniques with Your Sewing Machine
There are several hemming techniques you can use with a sewing machine, each offering a slightly different look and finish. We’ll focus on the most common and easiest for a simple hem.
The Double Fold Hem (The Most Common Method)
This is a very popular and durable way to hem a garment. It involves folding the fabric edge twice, encasing the raw edge within the fold. This technique is excellent for various fabrics, from cotton shirts to slightly heavier materials.
Steps for a Double Fold Hem:
- Prepare the Fabric Edge: After cutting, you should have a raw edge.
- First Fold: Take the raw edge of the fabric and fold it up towards the inside of the shirt by your first marked fold line (usually about ½ inch or 1.2 cm). Use your iron to press this fold firmly in place. This will create a crisp crease.
- Second Fold: Now, fold the fabric up again along your second marked fold line, encasing the raw edge. Press this fold firmly with your iron. You should now have a clean, double-folded edge.
- Pin in Place: Secure the folded hem with pins. Place pins perpendicular to the folded edge, about every 2-3 inches (5-7 cm). This keeps the hem from shifting while you sew.
Setting Up Your Sewing Machine for Hemming
Correctly setting up your machine ensures a smooth sewing process.
- Install the Right Needle: For most shirts, a universal needle (size 80/12 or 90/14) is suitable. If you’re working with very delicate fabrics like silk or rayon, consider a finer needle. For knits, a ballpoint or stretch needle is recommended to prevent skipped stitches or fabric damage.
- Thread Your Machine: Ensure your sewing machine is properly threaded with your matching thread. Check both the upper thread and the bobbin.
- Select the Stitch: A straight stitch is usually the best choice for hemming. Set your stitch length to a medium setting, typically between 2.0 and 2.5 mm. This provides a good balance of strength and flexibility.
- Test Stitch: Before sewing on your shirt, test your stitch on a scrap piece of the same fabric. Check for even tension, no skipped stitches, and a neat appearance. Adjust tension or needle if needed.
Sewing the Hem
This is where the magic happens. Sewing a straight line is a core skill in sewing machine basics.
- Position the Fabric: Place the pinned hem under your presser foot. Align the folded edge so that the needle will sew along the edge of the second fold. For a neat finish, you want to sew very close to this inner folded edge.
- Lower the Presser Foot: Ensure the presser foot is down.
- Start Sewing: Gently guide the fabric as you sew. Do not pull or push the fabric; let the machine’s feed dogs do the work. You can guide it with your hands, keeping them a safe distance from the needle.
- Backstitch: When you start sewing, backstitch a few stitches to secure the beginning of your seam. Do the same at the end of the hem to prevent it from unraveling.
- Sew Around the Hem: Continue sewing along the entire length of the hem. As you approach a corner or curve, slow down.
- Finishing the Seam: When you reach the starting point, backstitch again to secure the end.
- Trim Threads: Carefully trim any excess threads.
Finishing Touches: Pressing the Hem
Pressing is a crucial step that elevates your sewing from amateur to professional. It’s often overlooked but makes a significant difference in the final appearance of hemming a garment.
- Iron from the Inside: After sewing, turn the shirt inside out.
- Press the Fold: Press the hemmed edge flat. You can press the entire folded section to ensure it lays smoothly.
- Press the Seam Allowance: If your hem has a visible seam allowance on the inside, press it upwards against the main body of the shirt. This creates a very clean finish.
Alternative Hemming Techniques for Specific Fabrics
While the double fold hem is versatile, some fabrics benefit from different hemming techniques.
Hemming Knit Fabrics (T-shirts and Stretchy Materials)
Hemming a t-shirt requires a bit of care due to its stretchy nature. A regular straight stitch can break when the fabric stretches.
- Use a Stretch Stitch or Zigzag Stitch: Most sewing machines have a specific stretch stitch. If yours doesn’t, a narrow zigzag stitch (stitch width 1.0-1.5, stitch length 2.0-2.5) is an excellent alternative. This allows the seam to stretch with the fabric.
- Use a Twin Needle: A twin needle is a fantastic tool for hemming knits. It creates two parallel rows of stitching on the top and a zigzag stitch on the bobbin side, allowing for stretch. You’ll need a twin needle compatible with your machine and two spools of thread (one for the top and one for the bobbin, or two on top if your machine allows).
- Setup: Thread the machine as usual, but thread one spool through the regular thread path and the second spool through the second upper threading path.
- Stitching: Sew with the right side of the fabric facing up. The twin needle creates two straight stitches on top, and the bobbin thread forms a zigzag between them on the wrong side, providing stretch.
- Stabilizing Knits: Sometimes, knit fabrics can curl or stretch out of shape as you sew. Using a lightweight fusible interfacing or a stabilizer tape along the hem edge before folding can help.
The Rolled Hem
This technique creates a very narrow, delicate hem, often used on lightweight fabrics like silk, chiffon, or very thin cotton. It’s trickier to do with a standard presser foot, and a specialized “rolled hem foot” is highly recommended for ease.
- How it Works: A rolled hem foot has a small metal guide that folds the fabric edge into a narrow double fold as you sew, creating a rolled effect.
- Sewing: Feed the fabric edge into the groove of the rolled hem foot. The machine will then automatically fold and stitch the fabric. You’ll need to adjust your machine’s stitch width to accommodate the rolled hem.
Single Fold Hem
This is the simplest hem. It’s often used on fabrics that don’t fray easily, or as an inner hem on thicker garments.
- How it Works: The raw edge is folded up once and then stitched.
- When to Use: Good for very bulky fabrics where a double fold might be too thick, or on fabrics that don’t fray, like some felt or leather.
Troubleshooting Common Hemming Issues
Even with careful preparation, you might encounter minor issues. Here are some common problems and their solutions.
Uneven Hemline After Sewing
Problem: The hem looks wobbly or uneven after you’ve finished sewing.
Solutions:
- Check Fabric Handling: Ensure you weren’t stretching or pulling the fabric as you sewed. Let the machine feed the fabric.
- Use Pins Generously: More pins can help keep the fabric in place.
- Pressing is Key: A good press before and after sewing can help correct minor wobbles.
- Practice on Scraps: Work on your sewing machine hemming skills on scrap fabric until you feel confident.
Skipped Stitches
Problem: The sewing machine is skipping stitches, leaving gaps in your seam.
Solutions:
- Needle Type: Ensure you are using the correct needle for your fabric type. A dull or bent needle can also cause this.
- Needle Insertion: Make sure the needle is inserted correctly and all the way up in the machine.
- Thread Quality: Old or poor-quality thread can lead to skipped stitches. Try a fresh spool of good quality thread.
- Machine Tension: Check your machine’s tension settings. Sometimes the bobbin tension or upper tension needs adjustment. Consult your sewing machine manual.
Thread Bunching Up (Bird’s Nesting)
Problem: A tangled mess of thread appears on the underside of your fabric.
Solutions:
- Thread the Machine Again: This is the most common fix. Re-thread both the upper thread and the bobbin, ensuring the presser foot is up when threading the top thread.
- Check Bobbin Winding: Make sure the bobbin is wound evenly and is inserted correctly.
- Bobbin Case Tension: If your machine has a removable bobbin case, check its tension.
Fabric Curling or Puckering
Problem: The fabric edge curls up or puckers as you sew.
Solutions:
- Knit Fabrics: As mentioned, use a stretch stitch, twin needle, or stabilizer for knits.
- Pressing: Ensure you’re pressing each fold well before sewing.
- Slow Down: Sew more slowly, allowing the fabric to feed smoothly.
- Presser Foot Pressure: Some machines allow you to adjust the presser foot pressure. If it’s too high, it can stretch the fabric. Consult your manual.
FAQs About Hemming a Shirt with a Sewing Machine
Here are some common questions people have when learning to hem.
Q1: What is the best stitch for hemming a t-shirt?
A1: For t-shirts and other knit fabrics, the best stitch is either a stretch stitch (if your machine has one), a narrow zigzag stitch, or using a twin needle. These allow the hem to stretch with the fabric without breaking.
Q2: Can I hem a shirt without a sewing machine?
A2: Yes, you can hem a shirt by hand. However, it will be more time-consuming, and the finish may not be as neat or durable as a machine-sewn hem. For a quick fix, you could also use fabric glue or hemming tape, but these are not as permanent as sewing.
Q3: How much fabric should I allow for a hem?
A3: A standard hem allowance is usually 1 to 1.5 inches (2.5 to 3.8 cm). This gives you enough fabric to create a double fold for a clean finish. The exact amount can depend on the fabric weight and the desired look.
Q4: What is a “blind hem” and how is it done?
A4: A blind hem is a hemming technique where the stitches are almost invisible from the right side of the fabric. It’s achieved using a blind hem foot and a special blind stitch on your sewing machine, which catches only a few threads of the fabric on the fold. This is excellent for formal wear or garments where you want a very discreet hem.
Q5: How do I hem a curved hem on a shirt?
A5: Hemming a curved hem is similar to a straight hem but requires more patience. You’ll typically use a narrower hem allowance (around ½ inch or 1.2 cm) and fold it up in small increments, clipping the curve slightly if needed to help it lie flat. Pins are essential here. Some sewers find it easier to use a double fold hem, folding just ¼ inch first, pressing, and then folding the remaining ¾ inch, pressing again. Sewing slowly and carefully is key.
Q6: Why is my hem puckering?
A6: Puckering is often caused by the fabric stretching as you sew, or by improper tension settings. Ensure your presser foot pressure isn’t too high, you’re using the correct needle, and you’re not pulling the fabric. Pressing each fold firmly before sewing also helps prevent puckering.
