The 12" Add-a-Quarter Ruler is an essential precision tool for paper piecing and foundation quilting. Featuring a custom raised lip along one side, it automatically leaves a perfect 1/4" seam allowance every time you trim your fabric back.

• 12-Inch Length: Ideal for working on medium-to-large quilt blocks without needing to re-position mid-cut.

• Tapered Edge: Allows your rotary cutter to slide cleanly alongside the ruler for swift, straight cuts.

• Durable Acrylic: Made from clear, high-visibility acrylic for easy alignment over printed foundation patterns.
