Wonder Curve Ruler
Wonder Curve Ruler by Sew Kind of Wonderful. This 6" x 10" piecing ruler has colored lines and markings which makes it wonderfully simple to make a combination of curved blocks that are used repeatedly in WCR Patterns! These unique lines and markings make using the Wonder Curve Ruler as easy as, 1-2-3! The three bold-colored lines also make it easy to scale a block larger or smaller just by aligning the fabric with the different colors and marks.
