How it works

Three steps to your next quilt.

No manuals, no classes, no $240 desktop software. If you can take a photo, you can make a pattern.

1

Snap or upload

A photo, a sketch on kraft paper, a child's drawing — anything. Our AI reads the line work, keeps your paint-by-number labels, and never crops your design.

2

Refine in the Studio

An inch-accurate canvas with layers, snapping, and per-axis scaling. What you see is measured in real inches — not screen pixels.

3

Print & stitch

One click exports a compiled PDF, tiled across letter pages with match lines and registration marks. Overlap, tape, trace — every line meets perfectly.

AI stencil conversion

AI that understands seam allowances.

Plenty of AI tools make pretty pictures of quilts. They can't be sewn. Frog & Thread is different: it produces construction-accurate line work — closed piecing sections, preserved cutting labels, and geometry measured in inches.

  • Keeps your section labels (1A, 2B, CC…) exactly where you drew them
  • Full-image conversion — nothing cropped off the top or sides
  • Bold, continuous outlines ready for tracing or applique

Print-perfect tiling

Every page lines up. Every time.

The heartbreak of home-printed patterns: pages that don't match, line work lost in the margins, templates that print 2% off and ruin cut fabric. We solved it the way professional pattern houses do — then automated it.

  • Content duplicated in every overlap zone — ink on both pages at every seam
  • Dashed match lines + corner registration crosshairs for foolproof alignment
  • Neighbor arrows on every page — R2C3 always knows where R2C4 goes
  • One compiled PDF plus individual pages, organized in a tidy package

Studio & community

A full design studio — and the quilters to share it with.

Layers, vector blocks, LeMoyne stars, snapping, per-axis stretch — the Quilt Studio is a real design tool that happens to live in your browser. And when your pattern is done, a kind, moderated maker community is waiting.

  • Publish to your Showcase; collect reactions and "I made it!" from fellow quilters
  • Save inspiration to private boards; follow makers whose style you love
  • Sell finished patterns in The Pattern Book marketplace
  • No comment wars by design: emoji reactions only, human moderation

Questions, answered

Everything quilters ask us.

What is AI quilting software?
AI quilting software is a design tool that uses artificial intelligence to turn photos, sketches, or ideas into sewable quilt patterns — including piecing sections, cutting labels, and print-ready templates. Unlike AI image generators that only make pictures of quilts, Frog & Thread produces construction-accurate stencils with true ¼″ seam allowances you can actually print and stitch.
Is there an AI that can design quilt patterns?
Yes — that's exactly what Frog & Thread does. Upload any photo or sketch and the AI converts it into a quilting stencil with numbered sections, preserved labels, and closed line work ready for piecing or applique. It runs in your browser, so there's nothing to install.
Will my pattern print at the right size?
Yes. Every export is measured in real inches with a fixed ¼″ seam allowance. Tiled pages include dashed match lines, corner registration crosshairs, and duplicated overlap zones so adjacent pages align seamlessly when you overlap and tape them. Print at 100% ("Actual Size") and check one page with a ruler — it will measure true.
Does it work on a Mac?
Yes. Frog & Thread runs entirely in your web browser — Mac, Windows, or iPad, no download required. There's also a companion iPhone app with camera capture, so you can photograph a sketch and have it in your Studio before you're back at your desk.
How is this different from EQ8?
Electric Quilt 8 is powerful desktop software with a $239.95 price tag and a famously steep learning curve — there's an entire ecosystem of books and classes just to learn it. Frog & Thread starts free, runs in your browser, and does something EQ8 can't: convert a photo into a sewable stencil with AI. If you love EQ8's block libraries, keep it — many quilters use both.
Do I need to install anything?
No. Create a free account, upload a photo or start a blank canvas, and print your first stencil in minutes — all from your browser.

Your next quilt starts with a photo.
