Frequently Asked Questions
- Why is an 18" square ruler specifically useful for quilting?
- 18" is large enough to square up most standard quilt blocks (including 12" blocks with seam allowances), to cut blocks from fat quarters efficiently, and to check the squareness of quilt top corners. It’s the most practical large square ruler size for the majority of quilting applications.
- Can this ruler be used for squaring up a full quilt top?
- For squaring corners of a full quilt top, yes — place the 18" square ruler at each corner to establish the square corner line, then use a long ruler to complete the trim. The square ruler establishes the 90-degree angle; the long ruler completes the cut.
- Does the non-slip coating work on all fabric types?
- Yes — Quilters Select non-slip coating grips both standard quilting cotton and smooth-finished fabrics. On very smooth synthetics, test the grip before production cutting.
- Is there a difference between this and standard acrylic square rulers?
- The non-slip coating is the primary differentiator — standard acrylic can slide on fabric during cutting, especially on smooth cotton. The Quilters Select coating provides superior grip without adding thickness.
