I have a few 40 x 30 prints I would like to mount as inexpensivly as possible for a short exhibition. Any suggestions for doing this for as little $$ output as possible? I was considering sandwiching between sheets of plexiglas, but not sure how to fasten the 2 sheets together. Any thoughts?
Your idea of using two sheets sounds good and museums sometimes use that method. You might check with a museum or plastic shop about how it is done. I've also thought of mounting on aluminum or masonite.
