Here's my latest hat pattern - it features a braided edge and uses three colors. (It is
HERE on Ravelry and
HERE at the Lulu store.) Below is the women's size in Brown Sheep Nature Spun sport weight - Snow, Evergreen, and Butterfly Blue which is my favorite yarn color of all time.

This is the men's extra-large version for DH knit in organic Vermont O-Wool Classic in Cornflower, Saffron, and Sky.

The hat has a very easy four point top.
