Finished the second Chaz Hat. This one was the right size. Just cast on 124 sts, 2X2 rib for 8 rows, then alternated the colours until it was long enough. Decreased by (K9, K2tog) to last 3 sts, k; then (K8, K2tog) to last 3 sts; and so on until, (K1, K2tog) to end, then (K2tog to end). Very simple but it turned out nice.
And here is a picture of Smem in her blue dress. I think she likes it!
