I have always referred to this pattern as Flying Swallows, but it actually has lots of names: Falling Star, Flying Star, Whirling Star, and Circling Swallows. Whatever you want to call it, it’s a beautiful pattern. Cathi (Quilt Obsession) has been piecing a slightly more complex block which has this star in the middle, and she has posted a wonderful tutorial on piecing the wreath (or swallow) sections.
I have kept the image at it’s original size of 20.5″ x 15.5″
Nice pattern, I’ve never seen it before!
