Then I should also say the hammer in the test needs to be the same. The hammers in Ron's post must of had too much glue put in the solution at pressing time. He wasn't separating fibers, he was putting holes in a resin/fiber block that had no elasticity. I think it's pretty obvious that if you take a tri needle and pepper the the top 3 mm of a hammer enough, the layer comes apart. I don't think you untangled the wool fibers to get that to happen. I think the fibers are breaking.
