Command strips are a great idea and don't damage walls
Thank you........ I'll give it a try!
Diane...I suggest small nails in 2x4s or command strips
I like to put a wire across the back then hang on a nail or hook by the wire. I secure witha bit of poster putty to make sure it doesn't become unlevel.
Cut out paper the size of your frames and arrange them on wall. Use a level. Once you are happy with the arrangement, hang the actual pictures.
