Small mirror tiles glued to fishing line with lights behind. This is fantastic.Such a cool easy idea. Would be great in a dorm room. Those after Christmas sales are perfect time to get a light set cheap for this DIY project!
Print pictures on old book pages. Looks amazing. You could use a book that has special meaning with the picture or maybe sheet music. Perhaps you would like your wedding picture placed on your favorite song from your wedding. Would make a great gift too.
