That's what I was thinking. The Foam board outside should be archival (if it's the same quality as the stuff we used when mounting photos "back in the day"), but the foam wasn't meant to touch the photograph, and as most foams do, it degrades. I would be leery of having it against fabric.
The coreplast probably doesn't take pins well, but I pin fabric to fabric, not into the board. That would leave the pin too perpendicular to the board and catch on things. Also,
AlaskaSunshine uses a clip of some sort. No pins required.
As I recall, she uses 4x6 1/2" and 7 1/2" x 11 3/4", but I ended up cutting both down for my shelves, so measure your shelves before you cut or have cut.
