This sort of thing is not really "my bag" but I tried it anyway and this is the result. It will change as I finish it but the centre part will likely remain the same.
I am going to do something with those round disks too but may cut some new ones out of a couple of the fabrics I used in the centre.
I may also square up the right hand side. It is a little mingy in a couple of spots and I think it needs a bit more heft. I will add at least another strip of the black. The whole thing is cockeyed and I do not mind that but I just think it looks a little stingy on the right side.
