Is there a "smoother" decrease than K2tog ?

[Debbie]

I am knitting a chemo cap for a friend and decreasing every row so the top will be shorter and rounder. Is there a decrease that would show less than K2tog every round ? It looks fine, I was just looking for somehting that doesn't show the decrease line so much.

I don't know of any that show less. I find the cleanest, least visible is the k2tog. It will show the decrease lines though and I don't think there is one that won't.
