Circles on Quilts Templates are used for quilting concentric circles. These templates allow you to quilt circles at 1/4" increments from 2" to 12". Can be used to make baptist fans. Using the single pin system, there is only 1 point of rotation, which reduces movement. Set includes: 2" to 12" at 1/2" increments (set of 2), and 2-1/2" to 11-1/2" at 1/2" increments (set of 2"). Compatible with all domestic sewing machines - with appropriate ruler foot.
