مسطرة مثلث 22-1/2 درجة من كرييتيف جريدز - CGRT225

Sewed up eight of these triangles for a half-circle Dresden plate and the 22.5-degree angle made the piecing incredibly precise. The ruler’s markings are crisp and the center point is clearly marked, which saved me a ton of measuring time.

The grid lines are crisp and the 22.5-degree angle makes it so easy to chain together 16 triangles without any guesswork. I whipped up a Dresden plate top in one evening and it came out perfectly flat, even with fussy prints.

The markings are crisp and easy to read, which really helped me line up my fabric correctly for a half-circle project. It’s a bit smaller than I imagined for larger circles, but works perfectly for 8-inch blocks.
