Project your pattern at true 1:1.
Cut and Sew turns your Mac and a projector into a cutting table. It beams your PDF sewing pattern onto the fabric at true scale — then has you measure a test square with a tape, so you know one inch projected is one inch cut.
Measure it. Know it’s right.
That verified-accuracy loop is the whole point, and it’s always free. Bumped the projector mid-project? Re-verify in under a minute.
- Test squareMeasure with a tape to confirm true 1:1 scale.
- Thick fabricA reversible correction so lofty fabric still reads true — without recalibrating.
- Line toolGrainline/line tool with live length.
- Clean projectionThe pattern goes full-screen on the external display while controls stay on your device — not screen mirroring.
Large-format or tiled — it just works.
Import a single A0/copy-shop PDF, or a multi-page tiled PDF and Cut and Sew stitches the tiles automatically. Drag a PDF onto the window to import.
- LayersShow only your size on layered patterns.
- PlacementPan, rotate, mirror, and nudge by an exact measurement.
- VisibilityInvert colors, pick custom projection colors, and boost line thickness.
- Seam allowanceProject a second cut line at an exact offset from the pattern edge.
- ProgressCheck off pieces as you cut; your place is saved.
If it’s a PDF, project it at true size.

Questions, answered.
How do I know the scale is exact?
Cut and Sew projects a test square that you measure with a tape. If it measures true, one inch projected is one inch cut. If the projector gets bumped, you can re-verify in under a minute.
Is Cut and Sew free?
Yes, it’s free to project, and calibration and scale verification are always free. Cut and Sew Pro adds print-at-home and copy-shop export, seam-allowance add/remove, and unlimited saved patterns — as a one-time purchase, or an optional $2.99/month auto-renewing subscription.
What kinds of PDFs can I import?
Single large-format (A0/copy-shop) PDFs, or multi-page tiled PDFs, which Cut and Sew stitches together automatically. On layered patterns you can show only your size.
Do I need a projector?
No. You can print at home on Letter, A4, A3, or Legal with a test square and assembly map, or export one true-scale file for a copy shop.
Does buying on iPhone unlock the Mac?
Yes. Cut and Sew Pro is a universal purchase, so buying on iPhone or iPad unlocks the Mac too.
What is Cut and Sew, who is it for, and what does it run on?
Cut and Sew is a pattern projector that beams a PDF sewing pattern onto fabric at verified 1:1 scale, using your Mac and a projector. It is for garment sewists, quilters, dressmakers, tailors, cosplayers and anyone placing applique, beadwork or rhinestones. To start, drag a PDF onto the window.
Measure once. Cut true.
