I love this idea from design*sponge for decorating a child's room.
design*sponge says reader Leah shared a great project she had for parents who are renters. She had a good friend who wasn't allowed to paint her home so she made these cute winnie the Pooh characters for her out of foam core and fabric. "I drew the basic shapes of Pooh, Piglet and Tiger on foam core, cut them out with a craft razor, then covered them in graphic print fabric that i felt 'looked' like the three characters. I used spray fabric adhesive to adhere the fabric to the foam core." She'll use 3M sticky tape to stick the characters to the wall. "The project cost me only about $30 bucks since I used fabric remnants."
I think this looks so great, much more original than painting a mural.
