Leave off the outer shapes and you have an 8-pointed star.
This was an amalgamation of all our thoughts about shapes with 45 degree angles and the magic of ridges of garter stitch exactly matching up with stitches.
Eight 45 degree angles fit together at a point to make a complete circle. The radiating spokes of this design had to do the same. It was a delightfully simple piece of geometry and an equally simple method of construction.
This is the only photo we have of the star version. Once the other shapes are added it is not possible to go back to the star.
