Your suggestion of a book with different quilting done on several of the same quilt pattern is basically what quilt guilds do and call it a quilt challenge. They take the same pattern and fabric, make several of the same quilt and different people quilt them in their own way. If you attend quilt shows, look for quilt challenges. You'll see up close how different quilting enhances or detracts from a quilt pattern. Take a camera along and take lots of pictures-far away and up close-to help remember.
