I used a Razertip unit to burn in the hair. I started on the rear legs burning in small c lines. I didn't like the way it looked, so I carved off that part and started over again burning in small s lines. I also used a gouge to carve the area around the ribs to break up that smooth look. Depending on the grain of the wood it made a difference on the heat setting on the burner. It's the first time I did hair like this, so I learned a lot. Next step is to paint the wolf.
