YOU SCANNED SPOOL

A short, slightly
obsessive guide to threads.

Spool is a made-up brand. Its code still works, which is the point. While you’re here, a little about the craft behind WovenQR.

Plain weave is the simplest pattern: each weft thread passes over one warp thread, then under the next. That’s the animation on our homepage.

Warp threads run lengthwise and are held tight on the loom. Weft threads travel across them. (Weft rhymes with “left”: it goes side to side.)

The number of threads in a square inch. Higher counts feel smoother, but past a point, more isn’t better. Same with QR codes: cleaner reads faster.

A QR code is a woven grid too: dark and light squares crossing in rows and columns, with spare threads for error correction.
