Quilt Size 60in x 60in. This quilt is made using just one layer cake plus background fabric. You will need a speciality ruler for making half-square triangles and we used the Creative Grids Multi-Size 45/90 and you will also need a Creative Grids Two Peaks in One triangle for making those half rectangles. The combination of the different angles creates the illusion of circles although only straight sewing is required. Uses Creative Grids .
