Circular quilt designs often feel like a math headache, especially when you are trying to cut dozens of perfectly tapered wedges that must meet seamlessly in the center. The Creative Grids® 15-Degree Wedge Triangle Quilt Ruler is the professional solution for constructing crisp, smooth circles, fans, and Dresden-style plates without the frustration of hand-drafted templates. Because this ruler is precisely cut to a 15-degree angle, exactly 24 wedges will form a perfectly flat 360-degree circle. Whether you are aiming for a soft, wavy border or a dramatic, starburst medallion, this ruler ensures every segment is identical, eliminating the puckering and wavy centers that ruin large-scale radial designs.
Key Features
-
15-Degree Wedge Precision: Specifically engineered so that 24 wedges form a complete, flat circle, while 12 wedges create a clean semi-circle.
-
Optimal Size for Detail: Perfectly proportioned to construct fans and circular medallion blocks that finish at a versatile, manageable size.
-
Exclusive Non-Slip Perimeter: The entire outer edge is lined with the patented Creative Grids translucent grip, which locks the acrylic securely to your fabric when you apply light downward pressure.
-
Built-in Seam Allowances: Each wedge is designed with the standard 1/4-inch seam allowance included, so your circular segments nest and sew together with absolute accuracy.
-
High-Visibility Grid: Featuring crisp black and white dashed markings that are effortlessly readable on solid light cottons, dark fabrics, and complex, high-contrast novelty prints.

Durable Acrylic Construction: Machined from thick, heavy-duty acrylic that resists chipping and warping, providing a rock-solid straight edge for your rotary cutter.
Why Customers Love This Tool
Customers who enjoy radial piecing and circular designs rave about how this ruler turns a complex "expert" technique into a simple assembly line. The biggest challenge in fan and circle quilts is accuracy—if your wedges are off by even half a degree, the finished circle will ripple and cup instead of lying flat. Quilters love this ruler because it removes that risk entirely. The non-slip grip is a major favorite, as it prevents the narrow, tapered tip of the wedge from shifting during long, precise rotary cuts, ensuring your points stay sharp and crisp.

Is the seam allowance included? Yes. The 1/4-inch seam allowance is built directly into the width of the wedge, ensuring your pieces will fit together perfectly without needing to add extra math.
