I made this one up for myself a couple of months back using a unique skein of orange cascade 220 wool. In the end sadly its a little too snug and rides up my head. I guess I'll just have to make myself another one.
Here it is being modeled by my little man. Orange is his favourite colour.
The pattern is
Triobite by Hanna Ingalls.
Here is a detail of the pattern for those interested.
