Square and triangles are basic building blocks in quilting. Arrange shapes in colorful combinations for great quilt designs. Two Half Square-2" Finished sewn together form a 2" finished square. Use the squares and triangles to create 4-Patch, 9-Patch, stars, pinwheels, borders and more. The number of layers you can cut is determined by the thickness and type of fabric. Always start with fewer layers and build up. Use with Go! Fabric cutter and 10" x 10" cutting mat Shop Accuquilt GO! Dies, Cutters & Sets FREE SHIPPING Included On GO! Dies ONLY!
