A small studio,
obsessed with charts.

StitchingLab is a free image-to-pattern converter and a growing community catalog of free crochet patterns. It exists for one reason: turning a photograph into a stitch chart should not require expensive software, a fast computer, or a sign-up flow. A browser is enough.

We take the craft seriously. We don’t use the word “cute.” We don’t cover the page in hearts. We built a canonical pattern notation (SLPN) so that every pattern in the catalog is portable, lossless, and indexable — like FEN for chess positions, except for crochet, cross-stitch, and knit colorwork.

The catalog is community-generated by design. Every pattern you see was made by a real maker running a photograph through the converter and choosing to share it. We do not aggregate from third-party pattern sites. We do not commission designers. The work belongs to the makers.
