To account for fingering weight, cast on 130st and added one repeat. The finished hat was slouchier than planned, so additional repeat unnecessary.
Repeats: k 1 round main color, p 4 rounds main color, then k 4 rounds contrast color (to avoid seeing purl bumps of the contrast color).
Next time: I’d also knit jogless stripes and carry the yarns to decrease the number of ends to weave.
