4-N-1 Machine Quilting Ruler

The 4-N-1 machine quilting ruler is a must-have for machine quilting—perfect for quilting large curves, small curves, and straight lines all with one versatile tool. Designed by professional machine quilter Natalia Bonner, this ruler is one of Natalia’s go-to favorites and a staple for creating a wide variety of quilting designs with ease and confidence.

The 4-N-1 measures 10.5" in total length and 4.75" in total width. The straight edge measures approximately 8". The top curve measures 2", and the two smaller end curves measure 1.25", giving you multiple design options in one ruler.

Use the 4-N-1 for both ruler quilting and marking—its variety of curves and straight edges make it ideal for everything from structured designs to more organic, flowing motifs.
