What I've been using as "stick" for my torso stickers is quite simple. Some of you are probably familiar with that tape you can buy at most hardware stores that is sticky on both sides. Its usually sold in with a pack of clear plastic that you stretch over your windows and doors that you will not be useing in the winter. Its an insulator. The tape that you use to stick the plastic to the wall is what I use. Works out great, and because its so thin, you wouldn't know that its there once the torso is all done.
