Using unnamed, worsted weight, indie dyed yarn. Modified gauge. Was intended for a child but came out too big. Fault of pattern? Maybe my maths.

Earflaps:
2 decreases every other row as in pattern;
When 6 stitches remain, on knit row, k2tog, ssk, k2tog.
Work I-cord for 12.5”.
Bind off: Purl, p2tog, slip first stitch over second, cut yarn.
