Inputs

Sizes are computed from these fixed inputs: sts per (in) 4.5, rows per (in) 6, head circ (in) 22, target length (in) 8.5, yarn worsted wool, needle US 7 / 4.5 mm circular + DPNs. A different gauge or stock makes a different size; the counts do not change.

Brief

“Please design a mustard yellow beanie with a slightly slouchy fit and a narrow 1x1 rib brim, ideally with a flat-ish crown that decreases neatly.”

Checks

The counts, part sizes and placement were checked by computation on 30 September 2026 (verified on attempt 1); the piece has not yet been made by hand. If yours comes out differently, tell us and we will look at it.
