Not sure how you were planning on using the decorative stitches. The largest they will go on most machines is about 9mm, which is less than half an inch. Decorative stitches are often used over seams, as in a crazy quilt. You can't use them for free motion, because the feed dogs control the the movement of the fabric to create the decorative stitch. You can do straight lines and gentle curves, but you need to practice on a scrap sandwich. The feed dogs are controlling the fabric movement, because you have layers (backing, batting & top), and the dogs are grabbing the bottom layer, the top layer may not go along with the movement of the feet and the design may be distorted.
