I make a lot of small projects, mainly 3"X4" and 4"X6". I paint the edge with metallic acrylic and put a little easel on the back. Hardly no cost and people love them. Here are 2 sizes of easels on 8 1/2X11. I buy 22pt chipboard (think shoebox cardboard) off ebay and laser cut them. Usually takes 3 passes at 500mmm. I clean the edges of soot with a dry paper towel and in a day or so they lose their burnt smell. I attach them to the back with a hot melt glue gun.
