Thanks for the information, the nine patch I figured out. And it is the same as your calculation. Now I have to think about the pinwheel. Hey, I have to say, I am just back from the dentist office had two teeth pulled, quilting kept my mind occupied, I figured the nine patch out while laying in the chair, were I there longer I might have given the pinwheel a go in my head. Who would have thought quilting would be good even sitting in the dentists chair. Something like calgon take me away....
