Matt, how does this relate to waulking the cloth? I was under the impression that waulking was necessary in the process making wool cloth. Without it the cloth would still change size and would not have the tightness of weave that we are accustomed to. I once worked in a wool mill and I cut a piece of fabric off the end of a run. I worked it a little on a washing board to tighten it up but it remained pretty loose weave. Thoughts and wisdom please.
