And then there were three...

I made another block, but modified the technique as joining the quadrants and getting a really even join is difficult. If it isn't even the spokes look strange. I used slightly wider strips and joined the foundation pieced sections into a circle before adding the centre and outer parts, thus eliminating the annoyingly tricky bit! not a very square photo.. just getting used to a new PC.
Had I thought of this sooner I could have also eliminated the joined sections in the centre which would be more pleasing.
