First do a decrease round that decs 4 sts so you have 160 to start with - k22, k2tog, k20, k2tog, k20, k2tog, k20, k2tog and 2 sts left at the end.
Then start decreases for the top
k8, k2tog around, knit a round plain.
K7, k2tog around, knit a round
k6, k2tog around, knit a round
keep going with 1 less st between decreases, and a knit round between the dec rounds. When you get to 3 sts between the dec, dec on every round k2tog on every round and when you're down to about 20 sts, then put the tail through all the sts. See if that's better
