Thanks guys. The matted wool hats are pretty easy. I use a couple of different round cutting burrs and a dremel for that. I just hold it 90 degrees to the wood and push down and try no to leave any flat spots. At one time I was doing it with my Flexcut tool, but i put a chip in a blade. Then spent two hours getting the chip out without overheating the blade. For a lighter texture on the wood, I have a few nails from six to 20 penny size with the points rounded. I lock the piece in a vice and use teh nails like punches, and hit them very lightly.
