Robin Ruth Design Angle Ruler for Quilting — 6"×14" Transparent Acrylic, Centered Angle Marks 33.75°–90°

Robin Ruth Design Angle Ruler is a 6" × 14" straight-edge tool with integrated angle markings from 33.75° to 90°, created to speed accurate template layouts and compass constructions for quilt blocks.

If you cut and piece geometric quilt blocks, this angle ruler collects the most-used degree settings into a single lightweight acrylic guide that stays aligned while you mark or draw. The angle graduations sit near the centre of the ruler so you can pivot a compass or mark arcs without shifting the straight edge; the durable, transparent material helps you see fabric prints and seam lines beneath. Sold individually and made in the United States, it’s designed to simplify repetitive angle layouts commonly found in Robin Ruth Design patterns.

How does this ruler improve accuracy when marking angles?

The ruler’s printed degree increments are positioned toward the centerline so your compass point and pen can align precisely with the angle reference. A clear straight edge minimizes parallax when you transfer lines to fabric or paper, helping keep seam allowances consistent.

• Centered angle markings for reliable pivoting with a compass
• Transparent acrylic reduces visual obstruction over patterned fabric
• Long 14" length supports extended straight-line marking
• Degree range covers the most common quilt block angles

Which angles are included and why do they matter for my patterns?

This tool spans angles from 33.75° up to 90°, capturing the specific cuts and wedge shapes frequent in Robin Ruth Design blocks and similar geometric quilts. Having those specific angles on one ruler removes the need to fudge or repeatedly measure, so repeat pieces match more consistently.

• Includes precise settings from 33.75° to 90° to match pattern instructions
• Useful for wedges, triangles, and composite blocks
• Reduces setup time when cutting multiple identical pieces

Can I use this ruler for compass or arc-based constructions?

Yes — the central placement of the angle scales makes it straightforward to use with a compass. The design gives you room to set your compass point at the angle pivot and draw arcs or seam guides without the straight edge getting in the way.

• Centre-aligned scales allow clean compass placement
• Durable surface stands up to light marking tools
• Works for both drafting paper templates and fabric marking

What materials and dimensions should I expect?

The ruler is made from transparent acrylic for visibility and a consistent cutting surface; it measures approximately 6 inches by 14 inches, offering a balance of reach and control for hand-held layout. It’s lightweight enough to maneuver yet long enough to draw straight lines across larger pieces.

• Approximate size: 6" × 14" (15.2 × 35.6 cm)
• Material: clear acrylic for visibility and durability
• Manufactured in the United States

Who is this for: Quilters, pattern designers, and craft hobbyists who regularly work with angular blocks or templates will find this ruler saves measurement steps and improves repeatability. It’s especially helpful for makers following Robin Ruth Design patterns, teachers demonstrating block construction, or anyone who needs reliable angle references while drafting, cutting, or marking fabric and paper.
