Perhaps you should consider a waterproof heat proof cover on the board (plywood) and then a padding before applying the wool. I have an afterthought what is the plywood treated with? You would be heating that and breathing it.

It's now about 9 years old. And I spray my fabric with water instead of steam with the iron and spray starch when I need it. My wool mat is 17 x 24. I hang it up using a plastic clip hanger. But that's mainly to get it out of the way, flat, and readily available.
