Handi Quilter Dual Edge Ruler

The Handi Quilter Dual Edge Ruler is a precision longarm quilting tool designed for quilters who want to stitch consistent, flowing curves across their quilt tops. Compatible with any brand of longarm quilting machine, this double-edged acrylic ruler features two undulating wave profiles that guide the needle through long, soft curves ideal for spine motifs, wave patterns, and continuous line designs. Whether you are new to ruler work or building out a full template collection, the Dual Edge Ruler is a reliable, versatile addition to your longarm toolkit.

Key Features

• Double-edged design provides two distinct undulating wave profiles in a single ruler, expanding your design options without adding extra tools.
• Made from high-quality 1/4-inch (0.25-inch) thick acrylic for superior strength, clarity, and long-term durability under regular quilting use.
• Measurements and markings are etched — not printed — directly into the acrylic in white, ensuring the lines remain accurate and visible wash after wash.
• Compatible with any brand of longarm quilting machine, making it a flexible choice for HQ, BERNINA, APQS, and other longarm systems.
• Designed for use with the HQ Ruler Base and HQ Sure Foot for proper ruler stabilization and consistent stitch-in-the-ditch performance.
• The two wave curves are well-suited for quilting spines, feather stems, ocean waves, and other flowing motifs across large quilt sections.
• Formerly marketed as Wave B, this ruler carries forward the same trusted profile with the updated Dual Edge Ruler name and branding.

Frequently Asked Questions

Is the Handi Quilter Dual Edge Ruler compatible with longarm machines other than Handi Quilter?

Yes. The Dual Edge Ruler is made from standard 1/4-inch acrylic and is compatible with any brand of longarm quilting machine. You will need a ruler base and a ruler-style hopping foot appropriate for your specific machine brand and model.

What accessories do I need to use this ruler?

Handi Quilter recommends pairing this ruler with the HQ Ruler Base and the HQ Sure Foot. The ruler base stabilizes the ruler on your quilt surface, and the Sure Foot rides along the ruler edge to guide your stitching accurately.

Is this the same ruler that was previously called Wave B?

Yes. The Handi Quilter Dual Edge Ruler was formerly sold under the name Wave B. The design and profile are the same — only the name has been updated.

How are the markings applied, and will they wear off over time?

The markings are etched directly into the acrylic in white — they are not printed or painted on. Etched markings are permanent and will not wear off with regular use, washing, or handling.
