This and That Way hat uses 3 stranded knitting with a corrugated rib.

I ended up using a size 7 needle because I don’t normally work 3 stranded knitting, therefore my tension tends to be a bit tight. But if you’re experienced with 3 stranded knitting go with a size 6 needle. The size 6 needle hat fit me but was snug and just to give you an idea I have a 22” head circumference.

The middle band in the ribbing can be substituted with the other rib color or use scrap yarn from your stash. The middle rib color uses approximately 12 yards.
