I have several books of her's. If it is a single block quilt, they are great with good instructions and easy to follow. If it is a sampler quilt, forget about it! I am working on her barn quilt from the American Barns book. It is a nightmare and I have a friend helping me that has more than 30 years quilting experience. Some times she says to use a scant quarter inch seam and other times a 1/4" seam, she just never tells you when she is switching and that makes a big mess of your blocks.
But I have the book for the Day & Night block and it is so easy! But it is only about doing the one block.
