Here are a few creative ways to display photos... and easy! I've come across both these items a few times while scouring the DI for "trash to treasures." My favorite of the two is the metal matress springs.... the colorful clothes pins really make it pop! You could also spray paint the springs a bright color and make the clothes pins white... I have the perfect wall space in my own home for this project...
The old shutters are also easy to transform into a photo collage... what's best is there's no need to spruce them up - they're used condition only gives them more charm.
