I like this post at Elemental Cheapness in which Sabrina Mantle shares her creative ideas for reusing items to frame art. Creativity doesn’t end with the artwork — display can be creative too!
Most, if not all, of Sabrina’s examples come from cheap discounted, discontinued and As Is items from Ikea. That means what she shows may not be pieces you can actually snap-up yourself, but there’s plenty of inspiration for keeping your eyes open to possibilities… Discount isles, thrift stores, garage sales… Your own basement! You know I love thrifty ideas!
The most practical idea, shown below, is the simple use of glass, strung and hung with ribbon.
I also got a bunch of 7×9 pieces of glass with holes in corner (which I threaded ribbon thru) at Ikea’s As Is department for 50 cents each, just finished mounting photos on those for upcoming show I am doing, they look great!
I really like the idea — both in terms of aesthetics and the re-usability. Just slide the photographs and images out, and put new ones in, so it would be a great idea for art shows. (Acrylic options might be more suitable for ease in carrying about and careless shoppers.)
Authors bio is coming up shortly. 
Thanks for sharing! One thing to let your readers know though, the pieces of glass are one sheet and I glued the pic on to them. You can remove them and change but not all that easily, but still a cheap cool idea! Via la thrift!
