the last exhibition (i didn't co-ordinate this, but helped set it up at the venue and curate it) we had type setting boxes that held 25 cards, ung around the walls. they look really nice, each card has its own little box that it sits in. we had only 5 or 6 of these, and about 3-400 ATC's so the rest were mounted onto boards, and mostly directly to the wall in individual plastic diplay pockets, with double sided tape.
It will be a creative process itself, as we will work with the environment to make the best use of the space, what ever it lends itself to. if we have glass windows at eye level, that are very insulated, we couls stick them inpockets to the glass, so that they can be seen outside they gallery, and from both sides.
You can get plastic sheets with pockets in that, despite how they sound,look quite smart. these could be suspended and so you could see the fronts and backs.
if we can get free standing boards, we will probably use these too. it all depends on the space, resources and what we have permission to do.
We will probably look at the two venues next week, and whatever we decide, it will be consistent (you don't want too many dispaly methods or it looks messy).
One venue we are thinking of is very central, well known for the arts, and has a lovely, pure white decor and lots of natural light. there is plenty of open space and wall space on which to apply our ATCs.
Yes it is very time consuming, and quite a commitment, but to see the finished thing it is well worth the effort.
