I would look at several books containing antique quilts to see how they were quilted. Utilitarian or everyday quilts sometimes had an allover Baptist fan, clamshell, or grid pattern. I'm a hand quilter/beginning machine quilter, so I'm not an expert on what patterns to use with the large machines. As for border designs, you might want to look at all of the design elements within the quilt and use some of these as an idea for your border quilting design. Judy in Torrance
