There is another snowball type block that is really cute. It has corner triangles in the upper right and lower left corners only. The result almost looks like a bird in flight.
I've seen it done in one print for the snowball and a matching color for the corners,
and also done as various prints for the snowballs with one solid for the corners and also with several solids for the corners.
Maybe someone here can tell you the name of the pattern.
