As a result of the fact that you don't have to watch the sewing machine needle, more precise sewing is easy. Look at the Petite Applique stitch and how small it is in comparrison to the sewing machine needle. If you had to watch the needle to sew a stitch that small, you would take a very long time and miss the edge of the fabric no matter how hard you tried.
