Acrylic Arc Etched - Free Motion Quilting
Acrylic arcs are designed to help the quilter form beautiful long, smooth curves, often forming curved crosshatching. These arcs are tinted a slight blue that makes the etched lines easier to see. The templates also don't get lost like clear ones.
The etched lines are 1/4" apart. The proper line is etched to line up with the line you have just stitched taking into account the 1/2" foot diameter.
