Creative Grids 30 度三角尺 CGRSG1

My quilt circles have never come together this cleanly—the 19 1/2" size lets me cut multiple layers at once without slipping. Stitching 12 triangles into a perfect 38-inch ring actually worked on my first try, which surprised me.

I was worried about getting the angles right, but the clear markings on this ruler make it easy to piece a perfect 38-inch circle. The 30-degree lines are crisp and accurate, which saves me a ton of time on my quilting projects.

The 19½-inch length is perfect for laying out a full 38-inch circle without any guesswork, and those clear grid lines make matching triangle points a breeze. I finished twelve segments in an afternoon and the pieced arc came together seamlessly.
