So I've finally started painting the arm fins. I have decided to strip the metal frame from inside, because it isn't working out very well and I am going to instead put in a extremely stiff interfacing on the inside once i finish painting each fin. I wasn't able to do the complete pattern like it is in the picture because 1) i am terrible at proportioning right when I am looking at something and than painting/drawing it. I always do it bigger. 2) I didn't have enough space anyway.
