I can buy fiberglass easily and cheaply, and glass is very strong. It is a material that will biodegrade, as well.
The vapor of epoxy is something I don't want to deal with. I cannot use polyester because of the foam I used. The Titebond III glue I am using is water*proof* even though it is water based.
The ridged roller I used to press the fabric into the glue, and the wire brush I used to roughen the foam are in the background:
As you can see above, the printing on the foam is quite visible right through the dried fiberglass surface. Which is a neat trick, since the fabrics are not transparent, and neither is the liquid glue.
This is the 10oz E-glass smooth foam sample:
