Maybe this would help me avoid putting so many nail holes in the wall when hanging pictures! When hanging a picture, put toothpaste on the frame where the nail needs to be, press it against the wall and voila! Put the nail there!
Instead of framing each photo individually, cover an photo mat with a collage of black-and-white photos, put colored photo in middle. LOVE THIS. Colored photo of mom & dad in center black & white of kids around them.
Simple frames of the same color in different sizes on off-set floating shelves with larger framed & matted photos hung on the wall make an attractive "Gallery Wall" layout. (Easy to change too.) Love the wall paint color as well.
