Cheap photo/poster mounting?

[Art Vanderlay]

Has anyone got any ideas of a good way to mount photos temporarily?

I have done some 18"x12" photos for my sister to display temporarily in a shop to promote what she is selling (she has rented one for a week), but we cannot get cheap clip frames locally the correct size to put them in, and to be honest she would rather not pay out for clip frames.

Any bright ideas that are better than just sticking them straight to the wall poster style?

cotswoldmounts.co.uk do mounts nice and cheap, give them a call and they'll work out with you what you need. 18" x 12" is slightly bigger than their largest standard one but I'm sure they'd be able to make some up.
