Tracing a pattern keeps the original intact, so you can sew a different size later, grade between sizes, or hand a copy to a friend's project without worrying about wear. It takes about as long as a cup of tea, and it is worth doing for any pattern you love.
Why Trace Instead of Cut?
Multi-size tissue patterns are the main reason. If you cut along the size 12 line, you lose the size 16 forever. Tracing also protects fragile tissue from pins and creases, and lets you add your own alterations without committing to them on the original.
The tradeoff is time and a bit of material cost. Tracing a fitted jacket with many pieces is a real afternoon's work. For a simple pattern you will only sew once, cutting may be a reasonable choice.
What You Need
- Tracing material (see the comparison below)
- Pattern weights or flat objects like washers, which beat pins for keeping layers still
- Fine marker or pencil, tested first for bleed-through
- Clear ruler and curved ruler for straightening wobbly lines
- Paper scissors, kept separate from your fabric shears
- Masking or washi tape for joining sheets
Choosing Your Tracing Material
No single material is best. It depends on how often you will reuse the copy and how much you want to see through it. This table covers general characteristics only, so check current specs on each maker's official site.
| Material | See-through? | Durability | Main tradeoff |
|---|---|---|---|
| Pattern or tracing paper (plain) | Good to moderate | Low to moderate | Inexpensive and easy, but can tear with repeated use |
| Non-woven, fabric-like tracing material | Moderate | High | Holds up to many uses, but may need low-heat care and can feel less crisp |
| Parchment or baking paper | Moderate | Low | Easy to find, but ink may smear and it can be slippery |
| Brown kraft or heavier paper | Poor | High | Sturdy, but you need a window or light box to trace through it |

How to Trace a Pattern, Step by Step
1. Prepare the Original
- Press the tissue on a low, dry setting (no steam) to remove creases. Check the pattern's own guidance first, and use extra caution with very old or fragile tissue.
- Find the size line you want. A highlighter on a photocopy, or a pencil dot on the tissue's margin, helps you follow it.
- Lay the pattern on a flat, clean surface and weight it down.
2. Lay the Tracing Material on Top
- Cover the piece with your material, leaving a margin on every side.
- Weight both layers. If the material is slippery, a few small pieces of tape at the edges will stop it creeping.
3. Trace Everything That Matters
Copy more than the outline. Trace these, too:
- Cutting line and seam allowance (if printed)
- Notches, dots and darts
- Grainline arrow
- Fold lines and "place on fold" markings
- Lengthen/shorten lines
- Piece name, size, pattern name and brand
Use a ruler for straight edges and a curved ruler for armholes and necklines, working in short, steady strokes rather than one long wobble.
4. Mark Notches Clearly
Draw notches as short lines extending outward. Cutting little triangles from paper copies is tempting but weakens the edge, so lines are safer.
5. Check Before You Cut Fabric
- Compare adjoining pieces: do the seams you will sew together measure the same length?
- Check that the grainline is parallel to the edge of your material.
- Lay the copy over the original to confirm nothing shifted.
If you traced between sizes, blend the lines smoothly and re-measure those seams.
Alternatives to Hand Tracing
- Window or light box: helpful for dense tissue or thick paper, and it only costs you a sunny pane of glass.
- Reprinting a PDF: if you have a PDF pattern, you do not need to trace anything. Print another copy. Our guide to printing and assembling PDF sewing patterns covers the test square and taping, and why a PDF sometimes prints at the wrong size helps if your scale looks off. Printer choice matters if you reprint often, so see Best Printers for PDF Sewing Patterns: Laser vs Inkjet vs Ink Tank.
- Photocopying at a print shop: fast, but check the scale against a known measurement, as copiers can distort slightly. It also raises the copyright question below.
Common Problems and Fixes
- Marker bleeds onto the original: test on a corner or scrap first, or switch to pencil.
- Copy keeps shifting: add more weights and tape the material down at the corners.
- Lines look uneven: trace lightly first, then go over it with a ruler.
- Copy tears at corners: reinforce with a bit of tape, or use a more durable material for patterns you will use often.
A Note on Copying and Sharing
Tracing a pattern you own for your own use is common practice, but terms vary by designer and country. Check the pattern's terms of use. Passing traced copies to others or selling garments made from them may be restricted. If you are unsure, ask the designer or consult a legal professional.
Keep Your Copies Organized
A traced pattern is only useful if you can find it again. Fold or roll each set, label the envelope with the pattern name and size, and keep it with the original.
