Have trouble figuring out exactly where you need to hammer in a nail when hanging up a picture frame? The Industrial Cottage suggests using toothpaste. Simply dab a small amount onto the end of the picture hook, and gently tap the hook into the wall when you find the desire location for your frame. The mark left by the toothpaste is where you’ll need to put in a nail. Just remember to wipe off the toothpaste from the wall and from the frame when you’re done!
