MDF (Medium Density Fiberboard) for large art panels

[Chris Saper]

Hi Sharon,

Thanks so much for your nice comment over on the Unveilings section...I have indeed been following this thread (if anyone sees anything misspelled, I'm the culprit), and I might have to get off these lazy bones and try to make a board following your process.

To date, the approach I have used for large pastels is to have my Wallis paper (I buy it by the roll, which is 46" x 10 yards, so I've never needed anything wider than that!) and have it dry-mounted to 4-ply rag, and the 4-ply rag dry-mounted to 1/2" Foamcore. I've had little bit of warping on large pieces, but none to speak of in the sizes I most regularly work in (32" x 40" or smaller). In the future, I will have something mounted on the backside as well to minimize warping. With this approach, HUGE work is feather-weight.

Getting out of my comfort zone with materials is definitely a short suit of mine, but in this instance, I might just go for it.

Thanks to you, and all, for putting so much time into this very informative thread.
