Drafting a Spinning String Star Block

I am trying to draft a block and this is what I have so far tested in paint. Why did I use ms-paint instead of QE7, well... I didn't have my lap top at the time this inspiration hit me :) The design in real life will be a perfect 12 inch square finished (12.5 unfinished).

Using 1.5 inch strips and the center from a template I am drafting. Simple but dramatic, that's what I am going for and so far I think it's close to what I have in mind. Once start cutting and sewing I will know for sure.
