Here are the materials I used to build these frames. You can find these from a number of other suppliers but I've listed where I found mine and what I paid.
Acrylic wall mount sign holders with no holes! $11 3/32" Clear Acrylic (nearly 1/8") Portrait Landscape Glue on a Acrylic wall hangers sawtooth
$0.45 Acrylic solvent applicator
(small) $3 Acrylic solvent
4oz $7 Clear rubber feet
1/2" tall $12/25, need 50, $2/frame
10x screws to mount the pictures on (any will work, or use picture hooks or whatever you want to mount with)
I used a laser to hang my photos. If you are only hanging a few photos and not a wall like mine then you might not need a laser.
