Yes, I was taught to use them when I started quilting my first Hawaiian quilt. I was using a 36" hoop and the teacher said rather than turning the hoop all the time, i needed to learn to use the hoop. It is easy and so convenient when needing to go backwards or sideways. They are also called tailors Thimbles and you can get them at their supply stores. Don't know where they are? ask a shoe repair man!!! :) Jan
