Use these unique interlocking circles to add or subtract seam and hem allowances to your sewing patterns. Available in cm or inches. Each kit contains circles to add from 0.5cm to 3cm or 1/4" to 1" and there are two options of centre hole for each: small for a pencil, large for a fabric pen.
They're very easy to use, just keep the edge of the circle on the pattern line. It doesn't matter how you keep it on the line - roll along a ruler, push it with your other hand, guide it with your finger - whatever works is the right way! The trick is to focus on the edge of the circle and not on your pencil. If you need more than the biggest circle, draw one line then use that as your guide to add another.
