That is totally awesome! I just use the 3M wall strips xD I haven't had any problems with them peeling the paint or leaving a residue
These are the best things ever made. I would seriously try them.
I use them at Christmas to hang stuff that otherwise would require that extra hole in the wall. And seeing that we just remodeled our house, I am forbidden to use a hammer. Just pull them off and no marks, no sticky stuff, nothing!
