This hat is a stash-buster designed to match my purl soho mistake rib scarf I knit several years ago.
Yarn: 150 (no brim) - 200 (3" brim) yards of sport-weight yarn. Shown in Purl Soho Mulberry Merino in Black Green.
Needles: US size 6 circular and DPNs.
Gauge: 23st per 4 in in mistake rib pattern
Size: Adult - the mistake rib pattern is pretty stretchy so this will fit most adults
