This block is called 'cathedral windows' . It goes together so easily, it almost makes itself! I loved doing this one! I have top stiched the window in green contrast on the orange. I might do the pieced center on my other block of this . This one is one square as the other is 4 squares stitched together. If you look on konda's blog you will see it. here is my pic it has come out a bit darker than in real life. This is for chey's quilt. I have yet to do my one and the next one is due tommorrow!
