This hat design is based on a tuck stitch pattern by Nancy Marchant.
It has dark stripes, some from ribbing to the top, some from the the top down in different lengths.

The hat shown is made with Filcolana Indiecita, 100% alpaca, and Mayflower Luxus Sock, a handdyed soft yarn.

I used 23 g of Indiecita and 11 g of Sock Yarn.
