Set of 4. Good Measure Templates feature a special nonslip backing and clear markings in two colors. They are wider than nested templates, making them easy to hold. This set gives you 4 internal circle shapes in 1/2’’ increments, quilting circles from 3-1/2’ to 5’’, and 4 external circle shapes in 1/2’’ increments, quilting circles from 7-1/2’’ to 9’’. The measurements on the templates refer to the quilted circles that will be produced rather than that that of the plastic. Use this set with Every Semicircle Sets 1 and 3 for a full range of circle size. To use the internal shapes on this template set you must be able to lift the machine's presser foot. These templates are designed for ruler feet that are 1/2'' in diameter.
