I've been making a lot of prints at 8x10 and I enjoy the look of an 8x10 print with a 16x20 mat. I'm wondering if it's at all logical to mount my 8x10s to a small board that is still overmatted with a 16x20 board rather than using two 16x20s. My thinking being I'd save some supplies and also have the ability to jump down to a smaller overmat if I was inclined to do so. What do you all think? Thanks.
