I just purchased from freestylephoto.biz a box of Lineco 1.25 inch Self-Adhesive Polypropylene Mounting Corners 250 count - Clear (Full View Corner) and some hinge tape. The biggest problem I have is no way to flatten my prints. But if your prints are flat already, then you could, for the duration of the display, get some 11x14 mat boards cheaply enough for 8x10 prints or A2 size, and this box of corners, and mount away. You could then mount, say the 11x14 sized works onto a large display board using the hinge tape with T-hinges. How you will fix all this t0 a rough surfaced wall is a whole nuther matter, but at least it won't be destructive to your work. >michael
