Overview
Inspired by the linear structure of the roof at Liberty of London, this hat is worked top down. A simple cable, highlighted more if using a single color, flows from the crown as increases are worked on either side. I wanted a marled hat so I used one skein each of Woolfolk Sno and Sandnes Garn Sunday to create a blended fabric.
