star into square

I had the idea of making something round,
so I started out with an asterisk block

and thought I'd add to it, make it more of a starburst 

After cutting again, turning the blocks around seemed more interesting, so I abandoned the starburst and went with the idea of a wonky square in the middle.

This needed something else, so I added triangles to make it a square in square. 

From circle to square---completely different from my starting idea.

Hope I can make it work with the second step.
