To be honest, I really wanted to call this block “Kapow Star,” or something like that, because it kinda reminds me of the stars in vintage Batman fight scenes. But perhaps the rest of you didn’t spend as many afternoons watching it as I did… :)
Basically, this is a sawtooth star within a sawtooth star, so there aren’t really any new construction techniques here. Just many more pieces! The top row in the diagram represents the outer (larger) star points, while the lower row represents the inner star:
Since we’ve done all this before, I’ll just direct you to the Basic Sawtooth Star tutorial for the order of operations. I found it was most effiecient to work on both sets of points at the same time. In the larger set the “geese” in the flying geese units are the background fabric, while in the smaller set the “geese” are the foreground fabric.
When you’ve finished up the flying geese units, and squared them up to 3-1/2″ x 6-1/2″ (larger) and 2″ x 3-1/2″ (smaller), put together the inner star first.
Square up the inner star to 6-1/2″, and then put together the outer star.
