Ginette, why not use archival foam-core? It' s nice and flat and stiff? And the print is not attached to the board, just to corners on the board.

I would use Woolfitt's but they do not supply Rising board anymore. When they did, it was $16 for a 32x40 board, Talus is as low as $10 or so but yes with expensive shipping. If I could find the Rising Photomount locally (Toronto), then I WOULD buy here instead of Brooklyn, although I really enjoyed the Brooklyn pizza tour when I was there a few weeks ago!
Corner the Pt/Pd print under the window mat. Don't use any kind of mounting tissue or glue.
