I have all her rulers and love them. I've made 3 or 4 Hunter's Star quilts - 2 color, 3 color and a scrappy one. Sometimes I have to split the difference on the blades , but when the whole star goes together and matches with another star, they are generally right on the money! Even if it is off a teensy bit, I've found that it goes together music easier and quicker than any other Hunter Star method I've used.
