Non-slip rings hold the ruler and templates in place for cutting accuracy, allowing you to move the rulers easily and keep them in exact position. Easy to read and use: The rulers are made of highly transparent acrylic, so you can clearly see the fabric under the ruler.

The square rulers feature a 30/45/60 degree angle system to help create patterns such as square, triangle, parallelogram, trapezoid, and more. Please remove the protective film from the ruler to achieve an optimal quilting experience. Durable material and easy storage: Made from high-quality 3 mm thick acrylic, these rulers are robust and long lasting. They include a hanging hole to keep your work surface tidy. Use cases: ideal for constructing patchwork blocks with exact seams, creating geometric quilt patterns that require precise angles, and aligning borders or sashes for accurate results.
