With the $49 (before 40% coupon of 50% off sale) Hobby Lobby Exhibition frames, the backing is held in place by small metal bendable tabs. If I want to display the other side of the uncut, I can take the back off, flip the sheet, and have it back on my wall, with a different look, in about 60 seconds. I thought about the "Which side to display? Can I change what's viewed later on?" option before I went to these frames. I am up to about 20 framed sheets, with another 4 or so coming through KS pledges. Also, if you use Command Strips to hang them up, as opposed to nails, there's no wall damage, they are easy to take down for switching the sheet side, they never lose level, and you can easily move frames around to change the display order of your collection. Cheap, classic and expensive looking, sturdy, highly adaptable and flexible...hard to beat.
