The No. 712 is an English #12 size (U.S.A. size #0) small open-end sewing thimble. This size is suitable for use on a small-sized finger. These thimbles have several features that make them useful for carpet sewing purposes. The outer surface includes a coarse grate for pushing a needle point. The open end helps the thimble stay on and exposes the fingertip for gripping and other purposes. Formed from brass, and nickel-plated. Sold by each thimble.
