We've discussed our love of wall decals, but wall murals may be even more amazing. In addition to being unbelievably easy to apply, the decals allow commitment phobes to choose a theme for their tot's room and not feel guilty when they decide to change it a year later. Wallies Big Murals make it even easier to decorate your lil one's room with its life-size decals that stick right to your walls, without ever injuring them. The company's large decal sheets come in all kinds of kiddie themes — from princesses ($32) and flowers to surf boards and medieval castles. Smaller decals are also available for accent images, allowing you to make your child's room look like you had a mural custom designed just for them.
