Well, this experiment was a bust. The wool stuck to the aluminum foil more than they stuck to each other. I am thinking of trying it again, using the adhesives full strength instead of watered down (and on freezer paper or non-stick craft mat). I may still need to water down the Omni-gel as it is pretty thick and I don't think it will get through all the layers without being more viscose.
I am sure I can figure out a way to make this work somehow. I may try wallpaper paste as well.
