EZ Quilting rulers, templates, and tools are ideal for all of your quilting projects. Designed to work with a rotary cutter, they aid in cutting straight lines and perfect shapes. The rulers and tools are made from clear acrylic, allowing you to see the fabric underneath, and they're thick enough to prevent the rotary cutter from jumping over the edge. This two-piece acrylic tool makes creating quarter circle blocks a breeze.Details:ClearDesigned to be used with charm squares (5" x 5" fabrics)2-piece rulerIncludes easy-to-follow instructionsAcrylic
