مسطرة إسفينية

Finally, a ruler that actually stays put on fabric while I'm marking curves. The clear markings and non-slip surface made cutting out half circles for a quilted bag so much easier than using a compass.

I was skeptical about cutting perfect circles, but the non-slip grip held the fabric steady and I got a precise quarter-circle on my first try. The angle markings are so intuitive that I finally tackled a spiral pattern I’ve been avoiding.

The angle markings are incredibly clear and easy to read, which saved me from making waste on a tricky spiral cut. My wedge pieces came out uniformly sized on the first try, and the non-slip grip held steady even when I was pressing down firmly.
