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

“I'd love a bright mustard yellow beanie for my teenage nephew, plain all over with a 1x1 ribbed brim and a simple, snug crown. Nothing fancy, since it's only my second hat.”

Checks

The counts, part sizes and placement were checked by computation on 29 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.
