I look after an old church (bits go back to c. 950). I have made a set of interprative boards (200mm wide x 400mm tall) mounted on 3mm foam board and they need fixing to (mainly) stone pillars. It is clearly crucial that nothing is done that will damage the fabric of the place though I think I would get away with a picture-hook pin, driven into the lime mortar that is used.
It would be helpful if at least some of them could be easily lifted off if a board is thought to be "disturbing" during a service - so I don't want to attach them permanently.
My current thought is to use (where possible) the aforementioned picture hook pins without the actual hook part and a small picture hanging D-ring, attached to the foam board with some duct tape.
Is there a better solution?
