I staple parchment together to make a baking bag for salmon, and other delicate baking meats. I use it to line all my baking pans. I buy more parchment paper then foil. I buy it by the case in pre cut baking sheet size from a restaurant supply store. One case will last me for several years now that I don't bake as much. Wax paper will burn in the oven never line a cookie pan with it. A cake pan liner from wax paper will work, as long as the paper is completely covered in batter. For small parchment paper uses, use the muffin tin liners flatten out.
