The vacuum easel works great for keeping large sheets of paper flat, but anything above that paper it has no bearing on. If I were to put a sheet of paper on the easel and turn the pump on the paper goes flat, then I position the 8x10 neg over the paper and there's nothing to force the neg to make close contact with the paper. That's why I'll need a heavy sheet of 11x14 plate glass. The suction from the easel on the overlapping glass will also help put pressure on the neg/paper. I read somewhere where a person used a very large sheet of mylar on a vacuum easel and they said it worked fine.
