Skeinsong

Honest tools and lasting knowledge for fiber arts.

Machine-verified patterns. Tools that do what they say. Knowledge that doesn't disappear.

Our first tool

Frogproof private beta

Paste a written crochet pattern and Frogproof checks it stitch by stitch: counting errors light up with the fix spelled out, the chart draws itself, and a 3D preview shows the finished shape before you pull a single loop. Never rip out rows over a typo again.

Frogproof works entirely in your browser. No account, and your patterns never leave your device.

What's coming

The wiki: a free, open reference for fiber arts. A guided path from first chain to publishing your own patterns, a stitch dictionary, and every page downloadable so it can't vanish.
The archive: public-domain patterns from before 1931, transcribed, modernized, and machine-verified. A century of craft, checked and kept.
More crafts: what works for crochet is coming for its sibling arts.

Why "Skeinsong"?

Every yarn craft begins with a skein, and every pattern is a song somebody wrote down. Songs survive by being passed along carefully, verse for verse. That's the whole idea: pass the craft along, and get the verses right.
