Spin The Triangle Hunter's Design Studio Spin the Triangle is made from simple half-square triangles set into pinwheels. The large scale is both dramatic and faster to make. Two styles of half-square triangle construction are included in the pattern. Have fun choosing 6 fabrics to shade across the pinwheels! Multiple sizes. Baby: 39" x 39", Snuggle or Queen: 75" x 75", Queen or King: 111" x 111"
