Quilters Select Non-Slip Ruler 18in x 18in Large Square Block Squaring
The Quilters Select Non-Slip Ruler 18" x 18" is the large format square ruler in the QS line — designed for squaring very large quilt blocks (16", 18" finished), trimming large half-square triangles, and any block squaring task where the 10.5" ruler is too small. The 18" square is also valuable for checking and correcting the squareness of quilt tops before longarm loading.
Frequently Asked Questions
- What is the primary use case for the 18" square ruler?
- Squaring large blocks (14" to 18" finished), trimming large 10" half-square triangles, checking corner squareness on quilt tops, and any block squaring task that exceeds the 10.5" ruler’s capacity.
- Is the 18" square useful for checking quilt top squareness?
- Yes — placing the 18" square in the corners of a finished quilt top allows verification that the corners are true 90-degree angles before longarm loading. A square quilt top loads and finishes more cleanly than a distorted one.
- Is the 18" square a production tool for longarm studios?
- Yes — in addition to its piecing uses, the 18" square is used in longarm studios for client quilt preparation work to identify and correct square issues before loading.
- Is the non-slip coating important on an 18" ruler?
- Yes — an 18" ruler is heavy and prone to shifting during cutting without non-slip surface treatment.
- Should most quilters own both the 10.5" and 18" squares?
- Quilters regularly working with large blocks above 10" should own both. For quilters primarily working with 6"–10" blocks, the 10.5" alone may be sufficient.
