I don't want blue tack, but something better. I want to create a huge panel/wall (10' across and 6' high) of lightly backed photos of identical sizes that can be arranged and rearranged without damaging either the wall of the photos. Blue tack is just too sticky and does not allow the image(s) to be easily repositioned and sometimes leaves a mark on the wall. Any suggestions gratefully appreciated. This is part of a larger project for an old folks home to help with their memories and mental recall. via /r/DIY http://ift.tt/2sBcT6x
