Pretty! My only concern is that the etchings might get dusty / yellow faster....

i've seen this done with a cut piece of glass over the print, so that might help, greenlagirl.

For dusty yellowing the best thing to do is photocopy in color and you don't have to worry about ruining precious art and yellowing takes much longer I found. I have actually used paper clamps to hang some large black and white photos which were given to me from a photographer friend and it was a really cool industrial look

This would be great for nice greeting cards you want to save, and for doodles that you want to take to the next level that might otherwise get lost in a sketchbook or notebook somewhere and never used. Or those small ones in the kitchen for a few favorite recipes that get used often. Endless possibilities. Love this.
