Photo lab with oversized mounting backing?
So, I figured out a workaround. I placed my 8x12 print on a 12x16 (actually 12x18 and will have to trim as they don't offer 12x16) canvas and sent that to MPIX to be printed and mounted. Unfortunately, I have to pay for a much larger print, but I think it's still less expensive than having it dry mounted at a local framing shop.
