Etched lines are on the smallest arc in the set to guide curved crosshatching.
Acrylic arc set to guide the longarm hopping foot when making 12" - 23" circles and curves.

Renae's Amazing Arcs are 1/4" acrylic to guide your longarm machine in quilting circles from 12"- 23".  They are designed to aid in quilting the circles that are marked using Renae"s Amazing Rays and Renae"s Mini Rays. Each set comes with 6 acrylic arcs designed to stitch 12 circle sizes. Each arc will stitch 2 circle sizes. Each arc is 10" long and 2 1/4" wide for easily handling with your longarm. The circle diameter they are designed to sew is etched near that edge. They are designed to compensate for a 1/4" hopping foot on your longarm to achieve the diameter of the circle drawn with the Rays tool.
