I have a wet tanned long cut wt deer cape that I need to stretch. I bought the correct size manikin from ots but the cape is far from meeting on the incision. I knew it would shrink a little but I need to stretch it quite a bit. Wishing I had short cut, but its my first deer and wanted to make sure I did a good job fleshing, then I could have used a tire tube. How do you guys and girls stretch a flat cape?
