Teal Granny Square
Made

Photographed by Shea, November 2, 2026. A second photo, of the same piece with this record's card beside it, was reviewed by Krowtracks on November 2, 2026. The card didn't exist until the pattern was registered, so the piece was there after that. That photo stays private; its fingerprint is in this record.
Drawn from the stitches
Krowshea drew this from the pattern itself, stitch by stitch, with no photograph and no AI: the shape and colours the pattern makes. The symbol chart stays in the pattern. Yarn, hook and tension change how a piece looks, but not where its stitches and colour changes go: a photo that shows different ones wasn't made from this pattern as written.
What Krowshea checked
- Written in the Krowshea language and compiled stitch by stitch
- 192 stitches in 5 rows and rounds: every count adds up
- No errors or warnings
- Made: a photo of the piece with this record's card beside it, reviewed by Krowtracks
Where it comes from
- No earlier registration shares its stitches. Small and traditional rounds everyone uses (a magic ring of 6, a granny cluster) are not counted.

What this record means
- Shea registered this pattern on November 2, 2026, made it and photographed it with its card, and nothing in this record has changed since.
- The pattern can be made as written: Krowshea worked every stitch and every count adds up.
- Stitches belong to everyone: this record doesn't stop anyone using them. It shows who registered this pattern, when, and anything registered earlier that shares its stitches.
The card
No. 1 in Krowtracks. The card that went in the proof photo, now with the finished piece on it: download it to print, keep or share.
It shows what the pattern takes, who designed it and when it was registered. Its QR code opens this page.

The pattern-text fingerprint changes if one word changes. The stitch fingerprint stays the same when a pattern is reworded, put into UK terms or recoloured, which is how a copy is traced back to here.
