A step-by-step guide for quilting designers to convert drawings into cutting templates, covering preparation, the steps, and one tracing tool.

Convert a drawing into a cutting template by preparing a clean image, tracing it into vector shapes, checking the lines, and exporting a file your cutting software opens. VectorMagik is one tool that traces pictures into vector shapes. [1]

What you need before you start

Start with a drawing that has clear, dark lines on a plain background. A pencil sketch photographed in good light works, and so does a scan made at a sharp setting. Faint lines, blur, or shadows across the paper make the traced shapes wobble, so fix those before you begin.

Have the finished size in mind. Decide whether the template is a full pattern piece or a single block, and note the seam allowance you need. The traced line is the cutting line, so you will add the allowance as a separate step afterward.

Keep a ruler or a known measurement on hand, or record one real length from the drawing. You can then check the scale once the shapes are made. A notebook helps you track each size and each change.

Check which file types your cutting software opens before you trace anything. A file in the wrong format wastes a whole session.

Finally, keep an untouched copy of the original drawing. You may want to trace it again with different settings, and the original is your fallback.

Step by step

  1. Clean the drawing. Crop away the paper edge and any shadow, and make the lines dark and even.
  2. Set the scale. Measure one known length on the drawing and write it down, so the finished template can be checked against real size.
  3. Trace the drawing into vector shapes. Use a tracing tool that turns the picture into paths rather than pixels.
  4. Simplify the curves. Remove tiny pieces that a cutter will not need, but keep the corners and points that define the shape.
  5. Check the shapes against the original. Overlay the vector and the drawing and look for lines that drift.
  6. Add the seam allowance. Offset the cutting line outward by the allowance you chose, and keep the original line as a guide.
  7. Export and test. Save the file in a format your cutting software opens, cut one test shape from scrap fabric, and measure it against your ruler before cutting the full set.

Tools that can do it

VectorMagik is made by the team that publishes this site. It traces a picture into vector shapes using its own engine. [1] You can set how much small curve pieces are merged, and an automatic option picks the largest setting that still keeps the picture. [1] After converting, you can move or delete the points that make up a curve and round single corners. [1] You can limit the result to between 1 and 64 colours. [1] You can click shapes to delete them, such as a background, or merge two shades into one. [1] You can compare the vector with the original side by side, or flip between them with the B and V keys. [1] When you are ready, you can save the result as SVG, PDF, EPS, AI, DXF, EMF or PNG. [1] Downloads exist for Windows x64, macOS (Apple Silicon and Intel), and Linux x64. [1] A version also runs in the web browser using the same engine. [1]

This page describes only VectorMagik in detail. Other tracing tools are described only by their own sites, so check each one for what it does and what it costs before you choose.

Common mistakes to avoid

Tracing a blurry photo is a common mistake. Faint or shadowed lines produce wobbly shapes, so fix the source image first, because the traced shapes can only be as clean as the lines they come from.

Skipping the scale check is another mistake. A drawing photographed or printed at the wrong size gives a template that looks right on screen and cuts wrong. Measure one known length before you export.

Adding the seam allowance by eye is a mistake. Offset the cutting line as its own step and keep the original line as the guide, so the allowance stays even around each curve.

Saving only a PNG is a mistake for cutting work. A PNG is a picture made of pixels, so it does not hold clean cutting lines. Export a vector format if your cutting software opens one.

Assuming a free tool can be used for paid work is a mistake. If you sell the templates or use them in paid work, read the licence terms before you start. VectorMagik is free for everyone, and business use needs a licence (PolyForm Noncommercial 1.0.0). [1]

Frequently asked questions

How do you turn a drawing into a cutting template for quilting?

Start with a clean, sharp image of the drawing, set its scale with one measured length, and trace it into vector shapes. Simplify the curves, check the result against the original, add your seam allowance as a separate step, and export a file your cutting software opens. Cut one test shape from scrap fabric before you cut the full set, and measure it against your ruler to confirm the size.

Can VectorMagik trace a drawing into vector shapes?

Yes. VectorMagik traces a picture into vector shapes using its own engine. [1] You can then limit the result to between 1 and 64 colours and delete shapes such as a background. [1] [1] You can also compare the vector with the original side by side, or flip between them with the B and V keys, to check the traced lines before you export. [1]

Is VectorMagik free for quilting designers?

VectorMagik is free for everyone, and business use needs a licence (PolyForm Noncommercial 1.0.0). [1] If you sell templates or use them in paid work, read the licence terms before you start, so you know what applies to your work. The program is licensed under PolyForm Noncommercial 1.0.0. [1]

Which file formats can VectorMagik save?

VectorMagik can save the result as SVG, PDF, EPS, AI, DXF, EMF or PNG. [1] Choose the format your cutting software opens, and check that it reads the file before you cut a full set. After converting, you can also move or delete the points that make up a curve and round single corners. [1]

Does VectorMagik run in a web browser?

Yes. A version runs in the web browser using the same engine. [1] Downloads also exist for Windows x64, macOS (Apple Silicon and Intel), and Linux x64. [1] You can compare the vector with the original side by side, or flip between them with the B and V keys. [1]
