Binding off in the round is just like binding off knitting straight. At the beg of your round, k2 sts, pass one over the other, k1, pass one over, etc.
There are a lot of variations of feather and fan, the most common one is a multiple of 17 sts (your sts need to be divisible by 17 for it to come out right).
k2tog 3 times, (yo, k1) 5 times, yo, ssk 3 times, repeat all of that around.
