I just place my first order with MPIX and really don't have much of a clue what I'm getting, except that folks here talk nicely about the quality of the prints. I ordered a 16x24 with "Lustre Coating" mounted on "Double Weight Matboard". Has anyone else used that combination? Is it stiff enough to wall-hang without using a frame, and if so, what kind of clips/wire attachments have you used with success? I'm probably totally off base here - but I was kinda thinking about getting a bunch of photos mounted on just foamcore and plastering them all over a particular wall - but I'm not sure if what's coming from MPIX will work that way.
