Colleen's Cathedral Window project

Colleen made this pillow top using the method that Joyce found which we think is the method that Sharon used on her quilt and pillow which Sharon reports that Nancy Chan taught her some years ago.  Colleen thought that this was the method she had used on her Cathedral Windows project from the past but after making this project she says it isn't.  Seems like there are at least three methods for making a Cathedral Windows block.  This looked really good with very neat corners and can be entirely sewn by machine.  Colleen reported that the center square measurement as given in the tutorial is too small to cover the background so you should cut it about a half inch larger all around.  You have to look really hard to see that in the corners of Colleen's blocks, though.
