Quilter's Groove ProEcho Rulers

The ProEcho Rulers are ¼" thick and create a smooth curve providing a perfect ¼" echo. Because of all the markings these rulers provide, they are wonderful for curved crosshatching, continuous curves, and anywhere you may want a nice smooth curve. The numbers are based on a circle.... so for example the ProEcho 4... the curve comes from a 4" circle.  You can use them for spines, continuous curves, curved cross-hatching, block designs... anywhere that you need a curve.  

Available in 4 different sizes
