We store our works on paper flat, in a flat file. When exhibiting we attached the piece to a mounting board with a window mat over it, then place in a glazed frame. The linen tape is wonderful because it is strong, and reversible with water and a q-tip. When removed from exhibit, we would remove all traces of the tape on both the mounting board and the back of the work of art, then return the artwork to its original location. The mounting board is then re-usable. I would not use it for repairs.
