Getting Started: What Making Your Own Sewing Patterns Means

How do you make your own sewing patterns? You can make your own sewing patterns in a few main ways. You can draw them from scratch using your body numbers. This is called drafting sewing patterns. You can also start with a basic shape pattern that fits you well and change it. This basic shape is known as a basic pattern block or “sloper.” Another way is called draping fabric pattern making. This is where you shape fabric right on a body form. For beginners, drafting or changing a basic block are great ways to start making clothes that fit just right and look exactly how you want them.

Why Create Your Own Sewing Patterns?

Making your own patterns lets you make clothes that fit your body perfectly. Store-bought patterns often need changes. When you make your own, you start with your shape. This means fewer fitting problems. You can also make any style you can dream up. Want a unique neckline? Need a special pocket? Making your pattern lets you do that. It helps you truly understand how clothes are built. It is a creative journey where you are the designer.

Tools You Need to Make Patterns

To start making your own patterns, you need some basic tools. These tools help you measure, draw, and cut your patterns correctly. Having the right tools makes the work easier and your patterns more exact.

Pattern Making Paper: This is often wide paper. It can be plain paper, or it might have a grid on it. The grid helps you draw straight lines and right angles. LSI: pattern making paper.
Pencils and Erasers: You will draw many lines. Use a pencil so you can erase mistakes.
Measuring Tape: A flexible tape measure is a must. You need it to taking body measurements for patterns. You also need it for drawing your pattern pieces.
Rulers:
- Straight Ruler: A long one (like 18 or 24 inches) is helpful.
- L-Square Ruler: This ruler looks like an “L.” It helps you draw perfect right angles (90-degree corners). These are important for pattern edges and grainlines.
- Curved Rulers: French curves and hip curves help you draw smooth, curved lines. You use them for necklines, armholes, and hip lines.
Scissors: Sharp scissors are needed to cut your paper patterns. Keep them just for paper. Cutting fabric with paper scissors will make them dull for fabric.
Tape: Paper tape helps hold pieces together if your pattern is large or has many parts.
Pattern Weights: These are heavy objects you put on your pattern paper. They hold it still while you trace or cut.
Tracing Wheel: This tool has a spiky wheel. You use it with tracing paper to copy lines from one pattern piece to another.
Awl or Notcher: An awl makes small holes to mark points like dart ends. A notcher makes small cuts on the edge to show where pieces connect. LSI: pattern making tools.

Discovering the Basic Pattern Block

A basic pattern block, also called a “sloper,” is a fitted pattern. It has no style details like gathers, pleats, or flares. It just fits your body’s shape. Think of it as a second skin made of paper. You will have different basic blocks for different parts of the body:

Bodice front and back
Skirt front and back
Pant front and back
Sleeve

These basic blocks are the starting point for making any other pattern. Once you have a basic block that fits you well, you can change it in endless ways to create new designs. LSI: basic pattern block.

Grasping Body Measurements for Patterns

Getting the right numbers is key. Taking body measurements for patterns is super important. Your pattern will only fit well if your measurements are correct. Ask a friend to help you. It is hard to measure yourself accurately. Wear close-fitting clothes or just your undergarments when measuring. Stand straight and natural. Tie a thin string or elastic around your natural waist. This helps find your waistline easily.

Here are some key measurements you will need:

Bust: Measure around the fullest part of your bust. Keep the tape level across your back.
Waist: Measure around your natural waistline (where you tied the string). This is usually the narrowest part of your torso.
Hip: Measure around the fullest part of your hips and bottom. Keep the tape level.
High Bust: Measure around your chest, just above your bust. This is helpful for adjusting the bust area.
Back Waist Length: Measure from the bone at the back of your neck (base of neck) down to your natural waistline.
Front Waist Length: Measure from the top of your shoulder (near your neck) down to your natural waistline, going over the fullest part of your bust.
Shoulder Width: Measure across your upper back, from where one shoulder seam would meet the arm (shoulder joint) to the other.
Arm Length: Measure from the top of your shoulder (where it meets the arm) down to your wrist. Bend your elbow slightly.
Arm Girth: Measure around the fullest part of your upper arm.
Thigh Girth: Measure around the fullest part of one thigh.
Knee Girth: Measure around your knee.
Ankle Girth: Measure around your ankle bone.
Crotch Depth/Rise: Sit on a flat chair. Measure from your natural waistline down to the chair seat at your side.
Inseam: Measure from your crotch point down to your ankle bone (or where you want the pant hem to be) along the inside of your leg.

It is a good idea to write down your measurements. Keep them in a safe place. Re-measure every so often as your body can change.

Measurement	Where to Measure	Notes
Bust	Around fullest part of bust	Keep tape level
Waist	Around natural waist (narrowest part)	Use a string to find it
Hip	Around fullest part of hips/bottom	Keep tape level
High Bust	Around chest, above bust	Helpful for bust fitting
Back Waist Length	Neck bone to waist	Straight line down your back
Front Waist Length	Shoulder near neck, over bust, to waist	Go over the bust curve
Shoulder Width	Across upper back, from joint to joint	Measure bone to bone, not muscle to muscle
Arm Length	Shoulder joint to wrist (with bent elbow)	Follow the arm curve
Arm Girth	Fullest part of upper arm	Don’t pull tape tight
Thigh Girth	Fullest part of thigh
Knee Girth	Around the knee
Ankle Girth	Around the ankle bone
Crotch Depth/Rise	Waist to chair seat (when seated)	Helps with pant fit
Inseam	Crotch point down inside of leg to hem

Steps for Drafting Sewing Patterns

Once you have your measurements and tools, you can start drafting sewing patterns. Drafting means drawing the pattern pieces directly onto pattern making paper using your body numbers. This is how you create your custom basic pattern block.

Here is a simple idea of the steps, often starting with a bodice back:

Draw Base Lines: Start with a straight line down and a line across the top at a right angle. These lines are guides.
Mark Key Points: Use your measurements to mark points for the neck, shoulder, armhole, bust level, waist level, and hip level along these lines and out from them.
Connect the Dots: Use your rulers (straight, L-square, curves) to connect these points. You will draw the shape of the shoulder, armhole, side seam, waistline, and neckline.
Add Darts: Darts are folds sewn into the fabric. They shape the flat fabric to fit the curves of your body, like the bust, waist, and hips. You will draw darts onto your pattern piece based on your measurements and the design. For a basic block, darts shape the waist and sometimes the shoulder or armhole.
Add Markings: Draw the grainline (a straight line showing how the pattern should line up with the fabric threads). Add notches (small marks on the edges) where pieces connect. Mark dart lines.
Repeat for Other Pieces: Draft the bodice front, then the skirt back and front, sleeve, and pant pieces using the same method with their specific measurements.

Drafting a whole set of basic blocks takes time and practice. Many pattern making books have detailed steps and formulas for drafting different blocks based on measurements. Following a good book is highly recommended for beginners. LSI: Drafting sewing patterns, pattern making paper.

The Importance of Making a Muslin Fitting

After you draft your basic pattern block on paper, you must check how it fits on your body before you cut your good fabric. This is where making a muslin fitting comes in.

A muslin is a test garment. You make it using inexpensive fabric, often unbleached cotton called muslin (that is why it is called a muslin!). You sew the drafted pattern pieces together quickly, usually with longer stitches so they are easy to take out. Do not worry about perfect seams or finishing edges. The goal is just to see the shape on your body.

Try on the muslin. Look in a mirror. Move around. See how it feels.
* Is it too tight anywhere?
* Is it too loose or baggy?
* Are there weird wrinkles? (Wrinkles often point to fitting problems).
* Do the shoulder seams sit right?
* Does the waistline sit at your natural waist?
* Are the armholes comfortable?

Use pins to make changes directly on the muslin while you are wearing it. Pin out extra fabric where it is too loose. Let out seams a little where it is too tight (if you left enough extra fabric). Mark new lines with a pencil or fabric pen.

After the fitting, take off the muslin carefully. Lay the muslin pieces flat. Compare them to your original paper pattern pieces. You will see where you pinned or drew new lines. These changes show you what you need to fix on your paper pattern. LSI: making a muslin fitting.

Shaping Patterns with Dart Manipulation Techniques

Once you have a basic pattern block that fits, you can use it to make many different styles. One key way to change a pattern is by using dart manipulation techniques.

Remember that darts take flat fabric and shape it to fit curves. A basic pattern block bodice front usually has two main darts: one from the side seam pointing towards the bust point (side bust dart) and one from the waist pointing towards the bust point (waist dart). The bust point is like the pivot point for many dart changes.

Dart manipulation means moving the fullness that is in those original darts to a new spot on the pattern piece. The total amount of fullness stays the same, but where it is released changes the look of the garment.

Think of the bust point as the center of a clock. The dart value is the same, but you can move the dart opening to 12 o’clock (shoulder), 3 o’clock (side seam), 6 o’clock (waist), 9 o’clock (center front), or anywhere in between, like the neckline or armhole. You can also change darts into seams, gathers, pleats, or style lines.

Here are some simple examples of dart manipulation techniques:

Moving a Dart: Close the original dart on your paper pattern. Then, cut a line from the bust point to where you want the new dart to be. The paper will open up along this new line, creating the new dart opening.
Combining Darts: The waist dart and side bust dart can be combined into one larger dart or a seam.
Changing Darts to Gathers or Pleats: Instead of making a dart, you can close the dart on the pattern and slash the pattern to open up fullness where you want gathers or pleats.

Mastering dart manipulation techniques lets you turn a simple basic block into patterns for blouses with gathers, dresses with styled seams, or tops with different necklines without losing the good fit you built into your block.

A Glimpse at Draping Fabric Pattern Making

Draping fabric pattern making is a different way to create patterns. Instead of drawing on paper based on measurements, you shape fabric directly on a dress form (mannequin). The dress form should be the same shape and size as the person the clothes are for.

You pin and manipulate a piece of fabric (often muslin) onto the dress form, following the body’s curves and creating the design lines. You mark the edges, seams, and dart lines onto the fabric. Once the fabric piece is shaped correctly, you take it off the dress form. You then lay this shaped fabric flat on pattern making paper and trace its outline and markings. This tracing becomes your paper pattern piece.

Draping is great for creating designs with complex shapes, unique flows, or cowl necklines. It is a very visual way to design. For beginners focused on flat pattern drafting from measurements, draping fabric pattern making might be a next step after you are comfortable with drafting and manipulation. It requires a dress form and a good eye for shape. LSI: draping fabric pattern making.

Adding Seam Allowance to Patterns

When you draft sewing patterns or create a pattern using other methods, the lines you draw are the stitch lines. This is where you will sew the fabric pieces together. Fabric needs extra room beyond the stitch line so you can join the pieces. This extra room is called seam allowance.

You must add seam allowance to patterns after you have finished making all the design changes and adjustments to the pattern pieces. If you add it too early, it can make changing the pattern harder.

The amount of seam allowance you add depends on:
* The stitch type: Serged seams might need less allowance than standard machine seams.
* The fabric type: Fabrics that fray easily might need wider allowances.
* Where the seam is: Necklines and armholes often have smaller allowances (like 1/4 inch or 1/2 inch). Side seams or shoulder seams might have wider allowances (like 1/2 inch or 5/8 inch). Hems usually have much wider allowances.

You add seam allowance to patterns by drawing a new line outside the stitch line, parallel to it, at the correct distance (e.g., 5/8 inch away). Use a ruler or a seam allowance guide tool to help keep the distance even.

Remember to add seam allowance to all edges that will be sewn to another piece or that will be hemmed. Edges that will be on a fold of fabric do not need seam allowance. Also, mark fold lines clearly.

LSI: adding seam allowance to patterns.

Applying Pattern Adjustment Techniques

After making a muslin fitting, you will know what changes your pattern needs to fit better. Pattern adjustment techniques are how you make those fixes on your paper pattern. There are standard ways to change patterns to fix common fitting problems.

Here are some common pattern adjustment techniques:

Lengthening or Shortening: If a pattern piece (like a bodice or pant leg) is too long or too short, you cut across the pattern piece at specific points (often called “lengthen/shorten lines”) and spread the pieces apart (for lengthening) or overlap them (for shortening). Then, you true up the lines (make the edges smooth again).
Widening or Narrowing: If a pattern is too tight or too loose in an area (like the waist, hip, or sleeve), you can add width or take it away. This often involves cutting and spreading or overlapping the pattern piece from the edge towards a key point (like the bust point or hip curve) and then redrawing the seams.
Full Bust Adjustment (FBA): This is a common adjustment for bodice fronts if you have a larger bust than the basic block is made for. It adds width and length just at the bust area without making the whole pattern wider.
Small Bust Adjustment (SBA): The opposite of an FBA, taking away fullness for a smaller bust.
Adjusting Shoulders: Fixes for sloped or square shoulders.
Adjusting for Back Shape: Changes for a rounded or very straight back.
Adjusting for Hip/Thigh Shape: Fixes for different hip curves or thigh sizes on skirt and pant patterns.

Learning pattern adjustment techniques is key to making clothes fit you, not just a standard size chart. Many pattern making books and online resources show step-by-step guides for these adjustments. LSI: pattern adjustment techniques.

Finalizing Your Pattern

Once you have drafted, made a muslin, done fitting adjustments, and added seam allowance and markings, your pattern is almost ready.

True Up Lines: Check all lines to make sure they are smooth and connect correctly, especially after adjustments. Use your curved rulers.
Walk the Seams: Lay two pattern pieces that will be sewn together next to each other (like front and back side seams). Stand them on edge. Make sure the seam lines are the same length and curve smoothly together. This helps catch errors before sewing.
Add All Information: Write key info on each pattern piece:
- Pattern name (e.g., “My Basic Bodice Front”)
- Size or measurements used
- Grainline
- Cut instructions (e.g., “Cut 1 on Fold,” “Cut 2”)
- Any specific markings (darts, notches, buttonholes, pleats)
Cut Out the Pattern: Carefully cut out your pattern pieces along the outer lines (the seam allowance lines).
Store Your Pattern: Keep your patterns safe! You can hang them or fold them neatly. Use sturdy pattern making paper if you plan to use the pattern many times.

You now have a finished sewing pattern made by you!

FAQ – Common Questions About Making Patterns

h5 How long does it take to make a pattern?

It takes time, especially when you are new. Drafting sewing patterns from scratch and getting the fit right with a making a muslin fitting can take several hours or even days for a full basic pattern block. Changing a basic block or dart manipulation techniques might be quicker. The more you practice, the faster you will get.

h5 Can I copy a piece of clothing I already have?

Yes, you can. This is often called “rub-off” or “reverse engineering.” You lay the garment flat and trace its shape, seam lines, and details onto pattern making paper. You will need to guess where darts or shaping might be hidden in seams. This can be tricky, and the fit might not be perfect without adjustments.

h5 Is it hard to learn pattern making?

Like any new skill, it takes effort and practice. It involves math (measurements) and spatial thinking (how flat paper becomes a 3D shape). Starting with a basic pattern block and simple pattern adjustment techniques is a good way to learn the basics. Do not expect perfection on your first try!

h5 What is the best type of pattern making paper?

Beginners often start with simple dotted pattern paper or even large rolls of drawing paper. Oak Tag or pattern making paper with a printed grid is more durable if you plan to keep and reuse patterns. LSI: pattern making paper.

h5 Do I always need to make a muslin?

For new patterns or significant design changes, making a muslin fitting is highly recommended. It saves you from cutting into expensive fabric only to find the fit is wrong. Once you have a basic pattern block that fits perfectly and you are only making small changes, you might skip the muslin, but it is still the best way to check fit. LSI: making a muslin fitting.

Your Journey Begins

Making your own sewing patterns is a rewarding skill. It opens up a world of creative possibilities and the joy of wearing clothes that fit you perfectly. While it takes patience and practice, the process of drafting sewing patterns, working with a basic pattern block, taking body measurements for patterns, making a muslin fitting, applying dart manipulation techniques, adding seam allowance to patterns, and using pattern adjustment techniques builds a deep understanding of how clothes are made.
