Wonder Curve Ruler
This 6" x 10" piecing ruler has colored lines and markings which makes it wonderfully simple to make a combination of curved blocks which are used repeatedly in Wonder Curve Ruler Patterns!
Unique lines and markings make using the Wonder Curve Ruler easy as, 1-2-3! 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. Use this ruler with our Cool Cars pattern!
