Attach the thread and tie in the marabou. 

Add some flash sometimes I use flashabou and sometimes krystal flash, doesn't really matter.

Tie in a piece of schlappen, measure off where the back of the foam head is going to go. It looks a lot better if you wrap the schlappen tight to the back of the head. Lay down a thread base for the head to rest on and whip finish.

Glue on the head. I use a wooden kabob stick to make the holes for the eyes.

Glue on the eyes and add some rubber legs.
