This is pattern #6 from the simplysnowflakes Snowflake Signup.
The first round called for 24sc in a 6ch ring, then in the next round you had to work a stitch in each of these stitches. Tight! Too tight, in fact, so I worked 12sc instead and then 2sc in sc between each cluster instead of 3sc in all.
I don't think it made any appreciable difference. Except to my eyesight.
