The Perfect Piecer is a simple tool designed to help hand quilters achieve perfect points and even stitching lines.??The tiara-shaped acrylic template includes all the common angles used in traditional quiltmaking: 90°, 60°, 45°, 30°, 22.5°, 135° and 120°. Simply line up the correct angle on the Perfect Piecer with the shape you are stitching. Mark pencil dots through the holes and you will know exactly where to begin and end your stitching.??The 1/4" sewing line makes it easy to add seam allowance to templates or fabric patches.??Jinny uses the 45° angle side for marking miters, too! Ideal for checking every angle you cut and sew.
