Parchment Paper...not just for baking.
I do a lot of things with Hot Glue because I love how it sticks to almost everything. Well, one time I needed something that hot glue would not stick to. I tried wax paper but the hot glue melted the wax and stuck right to the wax paper. Then I tried parchment paper and that was the answer!! You can draw with the hot glue right on the parchment paper and it will peel right off. Now I keep a piece of parchment paper with my hot glue gun. I use it to catch the glue drips or if my gun falls over, I don't have to worry about it sticking to anything.
