Frequently Asked Questions
- What is an 18" x 18" ruler best used for in quilting?
- An 18" square ruler excels at squaring up large blocks (up to 17.5"), trimming the corners of finished quilts, cutting large background squares, and checking that HST blocks, flying geese, and other units are square before sewing them together.
- Is the 18" square ruler a good first large ruler to buy?
- Yes — it’s one of the most versatile large rulers. It handles tasks that a standard 6" or 12" square ruler can’t, particularly squaring large quilt blocks and checking overall alignment.
- Can I use this ruler to square up a finished quilt?
- An 18" square ruler is great for squaring corners of a finished quilt. For trimming the full width of a large quilt, a long rectangular ruler (such as 6" x 24") used with the 18" square gives the best results.
- Does the non-slip backing scratch my cutting mat?
- Quilters Select non-slip coatings are designed to grip without scratching self-healing cutting mats. Standard use will not damage the mat surface.
- What is the difference between the Quilters Select ruler and a standard acrylic ruler?
- Quilters Select rulers are thicker and heavier than many budget acrylic rulers, with more precise grid markings and a non-slip backing. The added thickness provides a more stable cutting edge for accurate rotary cutting.
