I always take an old shirt and pants and put them on the model. Make sure they fit snug. Then start wrapping the duck tape. If you have any exposed skin, make sure you powder it with baby powder so that the tape does not adhere to the body. Then when your all done, cut up the back or sides. After you cut them, stuff with old rags etc. and tape the seams back up. ****Footnote, before you stuff the mold, put a wooden hanger in the top, that way you can hang it later on. A metal hanger will not work!
