Quilter's Rule Ruler Quilting Templates 3/16" (4.5mm) deep

These rulers are all 4.5mm 3/16" deep to be used with domestic machines with a 'suitable ruler foot'. These templates work very well with 'low shank' feet as they give a little more depth for security than 3mm but should be shallow enough to pass under the shank without damaging the ruler of the foot.
