When it comes to wall decor, I am the chief hammer-wielder in our house. It's not because I'm good at it (I'm not); it's because my husband abhors even the idea of putting holes in our walls.
His feelings on the subject of holes would be one of the reasons I love this post from Pinterest on simple storage ideas. Not only are they inexpensive and easy, but many employ small (also inexpensive) plastic clips rather than nails.
Simple solutions. No holes necessary :-)
