Thanks every one, I am using 10" squares and and i did not want to have the bias so I made eight hst triangles. That middle seem for four put together is a lot of work , I am pressing it open to avoid the bulk in the middle. I am making 82 pinwheel blocks. I will probably half to cut down to 8". I am with you girls that the next time I will make bigger because I have to cut down anyway. I was tring to make them perfect so I would not have to cut down but that is impossible.
