We begin with a basic Star 60 unit, containing a diamond and two small triangles in 17 different size options, and then team this unit up with a multitude of additional shapes to create an array of amazing 60 degree quilt projects. Of course, you will find all the same benefits you have come to expect from every Studio 180 Design tool. There are multiple size options, oversizing and trim down for better accuracy, fine lines for higher precision, right and left hand instructions, free videos, supporting patterns, incredible design options, ease of use with other patterns, and an increased success rate for every level quilt maker.
