クリエイティブグリッズ マルチサイズ 45度・90度三角定規 CGRMS4590

The black markings against the white ruler make reading measurements so much easier, especially when cutting 45-degree triangles. I love that the math is already built into the markings, which saves me from doing calculations mid-project.

Finally, a ruler that shows you exactly where to cut without having to do the math yourself. The lines are crisp and easy to follow, even against darker fabrics. This thing will save me hours of head-scratching on my next quilt.

I've been using this ruler for my half-square triangles, and the built-in math on the 45 degree side saves me so much time measuring. The black and white markings are crisp enough to read even on darker fabrics.
