After the frame was completed I started to build up the form. Starting with the torso I placed layer upon layer of poly batting to build out a sort of simplified musculature. The arms and legs needed quite a bit more padding than the torso So I began building out the limbs with some cheap 1" upholstery foam. Fabri-tac and hot glue held it all in place. I didn't worry to much about using a super permanent adhesive since I knew that all the layers would be held in place with the final skin.
