I love this pattern -- except for adding sleeves to underarm BO sts. The first several rows after this addition are really tight and arduous. I believe I switched to a longer needle.

I had extra skein of all three colors and so was able to knit a matching beanie. CO 80 sts; start decrease after 4”; standard K2t beginning with K8, K2t around and knitting a row in between each increase round.
