Substrate idea

[Marla]

Also, I don't think it would be easy taking stains out of it.

There would be no need to, since I'd be replacing it like newspaper if I used it. I could almost build a house out of the amount we go through in a month here at work.

I was reading something else (probably the amphiliban book I got from the library) about how foams are often treated with flame retardant chemicals and that the chemicals can leech out in to the water.

Chemicals in the composition or coating and their effects particularly after getting wet or being heated were my biggest concern with using this stuff. The original post in this thread was made 10 months ago and I never did try it as a substrate. It just seems like there ought to be some use for the stuff besides throwing it away.
