Crooked Pictures?

Ever hang a picture only to find out that it will not hang strait? You can use a metal washer or coin to even it out. Secure the washer to the back of the high side of the picture at the bottom corner. Duct tape works great for this one. If you are worried about ruining the frame, you can also put one of those rubber knobbies that go on the bottom of objects to protect surfaces or on the back of cabinet doors so they don't make so much noise.
