I am framing an oooooold map, complete with wrinkles and creases and it is pretty fragile. So my thought is.... encapsulation.... however, I've read a lot about this but have never done it. I've read nearly all of the encapsulation threads in the past, and I have one glaring problem... can I buy Melinex by the sheet? This map is about 15 x 40, and I can't see purchasing a whole roll of it for one project. Any ideas, or options other than encapsulation?
