Foam retailer. Their prices aren't spectacular, but if you can't get it anywhere nearby, they've got it.

Nice! I had been looking for some Polyethlyene foam for crossguards etc. The only place I had found it was in random shipping crates we got for our tubo molecular pumps in the lab. Thanks for sharing!
