Trailer Machine Quilting Ruler

The Trailer machine quilting ruler is perfect for quilting straight lines, 45° angles, curved corners, and stitch-in-the-ditch with accuracy and control. Designed by professional machine quilter Natalia Bonner, this ruler is a versatile tool for adding structure and precision to your quilting designs.

The Trailer measures 12" in total length and 5" at its widest point. The notches along the bottom edge are designed to help guide stitch-in-the-ditch quilting and make it easy to visualize where your stitching will go—perfect for clean lines and consistent spacing.

Use the Trailer ruler for both marking and quilting—its straight edges, angles, and notches make it ideal for structured designs, borders, sashing, and detailed line work.

Charlotte G. ★★★★★ Oct 21, 2026

The 45° angle markings are incredibly clear, making precise corner cuts a breeze. I finished my latest quilt top in half the time thanks to this ruler.

Penelope T. ★★★★★ Oct 20, 2026

I was struggling to get consistent curved corners until I tried this ruler; the built-in guides made all the difference. It's solid under my hand and doesn't slip, which gives me a lot more confidence in my stitching.

Michael D. ★★★★☆ Oct 18, 2026

I was a bit skeptical at first, but the 45° angle markings on this ruler make diagonal quilting much easier to line up. The curved corner guides are a nice bonus for finishing blocks neatly. Only minor gripe is the ruler could be a tad longer for wider quilts.
