So, it's not too often that I go this crazy over a RULER. But let me tell you, I am in LOVE with the Quick Curve Ruler from Sew Kind of Wonderful. This 7" x 12" ruler is used to cut curve shapes out and square the blocks up after piecing. It is made from quality acrylic with a curve cut out where your rotary blade of any size will fit into it. Comes with a free pattern called "Urban Runner". Jenny Pedigo has a Mod Olives Quilt-A-Long going on that you have to check out! Just take a look at all the design possibilities...
