Tap, tap, tap. Too high, too low, or off center? I can't count the number of times I've put a nail in the wall only to pull it out and try it again. I've turned freshly painted walls into ones more suitable for a garage pegwall. Thank goodness for spackle, paint, and wall hangings. I have, however, found one way, aside from using a ruler and level, to make placing framed works on the walls a wee bit easier. The always talented Nate Berkus recently shared a tip that is so simple I don't know why I didn't think of it first. Instead of imagining your decorated wall and going straight to the hammer, cut out pieces of paper the size of your hangings. Then tape them to the wall and observe. When you're pleased with the visual, use a push pin to mark the spot where the nail should go. This is especially useful when placing more than one object. Your wall and future owners will thank you.
