This ruler is cut in our 1/8" sea-foam colored plastic for domestic machines.
This is a straight edge with a 12" finished arc side for curved or straight crosshatching. Angle lines of 45 and 90 degrees are marked on their respective sides. Lines on ruler are 1/4" apart, and the ruler is 8" wide.
We suggest getting some Grip Tape for a better hold on fabric.
