Wow! I saved Fall leaves last- Fall... flattened them in an old phonebook. 4 months later, they KEPT THEIR COLOR!!! Now what to do with them? I used them to decoupage the inside of a clear glass ginger-jar type lamp, using rubber cement. It came out gorgeous! White decoupage medium did NOT work on a test I did on a sheet of glass. Just framing them is also lovely, which I did for using in the same room. Oh boy, who woulda guessed they kept their lovely Fall colorings? I collected Tulip tree and Maple. Any other ideas?
