Quilting Stars

My grandmother was a quilter, and quilts need geometric designs to fit together well. In this quilt, there are beautiful stars. Stars consist of both concave and convex angles. These stars wouldn't be considered "regular" because they are uneven in length and angle measure. The exterior angle measure of these stars would not be 360 like a regular polygon (it is actually 401.48), because of the concave and convex angles, but they sure are pretty! (~CB1)
