Picture frame hanging tip: Stick a nail through a clothespin. Hang the photo from the nail attached to the clothes pin. Line up picture against wall. Lightly tap top of picture frame so nail leaves a small mark on the wall for you to hammer in a nail.
How high to hang pictures ~ center of frame should be from the floor if simply hanging on the wall. other links if you're hanging art above a sofa, fireplace, stairwell, etc.it drives me crazy to see pics way up in the wall!
Hammer nail through a wooden ruler. Hang picture on that nail. Line it on the wall where you want it. Remove picture, push in nail to make an indent. Remove ruler, hammer another nail into the wall Hang your perfect picture up.
Picture hanging tip: I discovered a great tool for hanging pictures with accuracy, sticky putty! Place two balls of putty over hooks on the back. Line the frame up and push onto the wall. The putty should stick to the wall, leaving you with a perfectly imprinted guide for nail placement. Just nail directly onto the putty. Pull the putty off and you have a perfectly hung picture!!!
