Achieving the perfect circular flow in a quilt shouldn't require complex geometry or hours of tedious drafting. The Creative Grids® 10 Degree Wedge Triangle Quilt Ruler is the professional’s secret weapon for creating stunning, symmetrical circular designs, fan blocks, and dramatic curved borders with absolute ease. Because this ruler creates a precise 10-degree wedge, exactly 36 of these segments will form a perfect, flat 360-degree circle. Whether you are constructing a high-impact kaleidoscope quilt, a traditional Dresden plate, or a modern circular medallion, this template ensures every single wedge is uniform, allowing your fabric patterns to flow seamlessly without puckering or distorting.

-
Fussy Cutting Guidelines: High-visibility black and white dashed markings allow you to perfectly center fabric stripes or motifs for vibrant, kaleidoscopic effects.
-
Built-in Seam Allowances: Each wedge includes the necessary 1/4-inch seam allowance, meaning your finished arcs and circles will maintain their intended size every time.

Why Customers Love This Tool
Customers love the 10 Degree Wedge ruler because it makes advanced curved piecing look effortless. Radial piecing—where you sew dozens of long, skinny wedges together—is notorious for causing quilt blocks to "cup" or ripple if the angles aren't perfectly precise. Quilters rave about this tool because the 10-degree increment is incredibly forgiving, and the non-slip grip ensures that when you are cutting long, narrow wedges, the ruler doesn't shift and ruin the point. It transforms an intimidating, "expert-level" technique into a fast, repeatable process that produces professional, show-quality results.

Frequently Asked Questions
How many wedges do I need to cut for a full circle? Because the ruler is set to a precise 10-degree angle, you need exactly 36 wedges to complete a full 360-degree circle.
Does this ruler include the seam allowance? Yes. The 1/4-inch seam allowance is already factored into the width of the wedge, so your pieces will fit together perfectly without any additional measuring or trimming.
Is it difficult to keep the wedges straight while cutting? Not at all. The patented Creative Grids non-slip grip is integrated along the outer edges of the ruler. When you apply light downward pressure with your hand, the grip locks the acrylic directly onto the fabric, ensuring the ruler stays perfectly aligned for the entire length of the wedge.
