Help! I am re-framing an old pastel on a board. The previous frame job was way too tight, the edges of the board were damaged from expanding and contracting, and it was glazed with acrylic so some of the pastel is still stuck to that. I am putting it in a sink mat.....
Here is my question. The board is warped on only the top left side. If I use one layer of foam core around it, everything except that corner fits fine. Do I use another layer of foam core or mat to accommodate the warped corner, or do I compress that corner to fit the thickness of the rest of the board? Will using too deep of a sink make the board warp more over time?

Please help...I have to finish this tonight!
