Framing drawings is the biggest pain in the butt. First of all, zero frames come in the standard 18"X24(26)" drawing paper. I chose some cheapo frames from ikea. I painted the wooden frames a black velvet finish. Because the cardboard is an eye sore, I also painted the illusion of matting. To anchor the paper onto the cardboard, I used a few drops of hot glue in the corner. The LAST an artist wants to do is place tape on the back of a drawing. The hot glue gun will hopefully just pop off the back of the paper when I am ready to put the drawings back in storage/portfolio, although charcoal drawings are safest within a frame. The slightest smudge can destroy charcoal drawings. This series of charcoal drawings do not have near the vibrancy that they had when I first completed them.
