This is a children's craft project; resembles stained glass. This is hilarious. I couldn't for the life of me figure out what I would do with that. Obviously I'm not very crafty. No, nothing adverse happens to the baked goods. I'm not sure if, in fact, "wax paper" is really "WAXED paper" these days, or if its been new and improved and modernized the way everything else has been. But used for lining, I guess there's sufficient insulation from both the batter and the pan that the wax paper stays intact, for want of a better word. However, you can't use it to line cookie sheets, since it will not tolerate direct exposure to heat. Only when there's a batter or dough covering it can you put it in the oven. I don't do much baking but this is handy to know, thanks.
