Handi Quilter Templates were created for use with mid-arm and longarm quilting machines of any brand. They are precision-made from high quality acrylic, chosen for its strength, clarity and durability. The 1/4 inch thickness provides safety when used with a hopping foot. Handi Quilter Rulers are always etched, never printed, to provide long-lasting accuracy. Handi Quilter Half-Circle Templates is a set of 6 half circle arcs cut in 1 inch increments from 1 inch to 12 inch. Each piece is marked with inner and outer edge size and with marks that can be used to align templates for perfectly quilted circles and arches. Package includes instructions for use, safety tips, and design ideas.
