I like to separate Double Star quilt blocks with either sashing or alternate blocks, because I'm not always fond of the way the star blocks line up with each other when sewn side by side, and because I think they look more like spinning pinwheels when they're separated a bit. This quilt is designed with sashing with cornerstones, but you can sew plain sashing if you prefer.
