This set of 4 templates quilts circles with the following diameters: 10'', 11'', 12'', 13'', 14'', 15'', 16'', and 17''. As with all of Amanda's templates, these feature a special nonslip back and clear marking in two colors. They are approximately 6mm thick (so, yes, they can be used with the BERNINA #72 foot!) With generous surface area, you'll find them easier to hold and the design possibilities are limitless. Lower those feed dogs and get quilting! These templates are designed for ruler feet that are 1/2” in diameter. GMAMESC3 Made in Wisconsin, USA.
