I must have over a dozen different thimbles. When I was at a quilt show in Walla Walla, WA, I saw the Clover thimble with the rubber or neoprene on it demonstrated, so I decided to buy and try. I love it! It stays on very well. The only drawback I've noted is that sometimes my thread gets caught in between the metal cap and the rubber, so I have to be careful or it will unthread from my needle.
