I have one and love it!!! When I first got it I was excited and had just finished an intense redwork. Put the piece face down so I wouldn't flatten the threads. It did stink and I got some stains on my redwork from the wool. Made me kind of sick. But, I didn't give up. I made a pillow case type cover, now I've been using it for a couple of months - no stink and no more staining.
