So hurray! I finished the hat. Moved on to the side of the face with the ear and the hair. I am hooking the hair with Butterfield 122 (8-value pack and texture pack).
It was very difficult to get the side of the face correct in terms of shadow and distinction. I rehooked the area about six times, and the hair twice. So I have been working on this small area of the rug all week. The good news is that I will take what a learned on this side of the face and apply it to the left. Maybe I won't have to rehook the left side so many times! We can only hope.
Sorry for the inferior photo, but my camera ran out of battery. So I had to use my phone camera.
