The Clover Protect and Grip Thimble is a wonderful alternative to traditional metal thimbles. With a scallop design, this thimble is made of flexible rubber for a gentle fit that allows comfort and ease of movement as you work. The thimble features a metal top that can be pushed firmly without danger, but with the rubber design, this is 50-80% lighter than a metal thimble. This thimble is available in small, medium and large sizes.MediumScallop designFlexible rubberClover Medium Protect and Grip Thimble. quilting sets for beginners
