Okay, this is wierd. I was just scrolling down to see a post where I could ask this exact freakin question and found this. I just got back from Home Depot where I bought some very thin plexiglass/plastic. I'm going to try 2 versions, 1 with the plastic, and 1 where I'm just going to use a shoebox chopped and reglued to size. If anybody has already done this, I know I for one would love any tips. As for glueing the artwork on, I've always had excellent results from using simple spray adhesive, since you get a very even cover that doesn't drip, and it bounds like iron. I'm going to give it a whirl this week, I'll check back for tips or let you know how it works on my end.
