Wonder Curve Ruler (WCR) by Sew Kind of Wonderful is a  6" x 10" piecing ruler has colored lines and markings, which makes it wonderfully simple to use while making a combination of curved blocks which are used repeatedly in WCR Patterns! The three bold colored lines also make it easy to scale a block larger or smaller just by aligning fabric with the different colors and marks. Wonder Flutters 10x37 pattern included with WCR.

Great patterns to try with the WCR Aunt Iris, Flower Pop, Park Place, Happy Together, Boho Holly,  Plant Life, and the Wonderful Curves Sampler Book.
