After way more hours than I thought it would take, I finished the skull with yarn. It looks pretty darn good.
My plan was to enter three pieces into a Day of the Dead show, 2 skulls with yarn and a shadow box. The deadline is today. I am obviously not going to get the other skull done today. I have decided to use felt on the other one which will be easier. I will finish that other one some time, since I won't make the deadline for the show. I am going to work on the shadowbox and see if I can get it wrapped up today so it can be entered. Wish me luck.
