Good info I will be using soon. precut mats are so expensive in stores. btw are 4ply mats a bit too thin? or ok for a temporary installation lasting 2-3 days?
I usually use 4 ply and think they're fine. The cheap ones you get with frames or at craft stores are 2 ply or less, so the 4 ply look better than that at least. I have a hard time cutting 8 ply myself.
