When I hung my Three Prophets prints above my living room sofa I decided that I wanted them to look like scrolls, so I devised an elaborate method involving two pieces of wood, some felt and three little screws. It also involved making a small hole at the top of each print -- OK for my own set of prints but probably not so cool for a print I hope to sell to someone else.
So here's another scroll-type mounting system I cooked up for showing the prints without harming them.
Materials: strips of wood, strips of acid-free mat board, binder clips.
I found some simple 3/4" pine moulding with rounded edges at Home Depot in the lumber section, which I cut about an inch wider than the prints. I sanded and stained the wood, then cut some 3/4" strips of spare mat board to the width of the print (not the extra width of the wood). The mat board protects the back of the print from the clips. For binder clips, I found some medium size clips in a classy brass finish that I thought would look nice.
Position a strip of mat under the print.
Position a strip of wood on top of the mat and the print.
Adjust this print sandwich until it's even.
Clip one side a couple of inches from the end of the wood.
Clip the other side the same way.
For a professional look, remove the squeezy handle thingies from the clips. Just pinch the handles together...
...and remove them from the clip. SAVE THE HANDLES so you can put them back in to remove the binder clips again later.
Follow the same procedure for the bottom of the print too, and voila!
Important note: Sharri LaPierre comments that wood is highly acid. She suggests that if the prints are mounted in this way for any length of time some kind of ph neutral barrier, such as glassine, should be added to the back of the wood where it touches the print. Very good point!
