Interested in a Bernina 730e but have been researching the 9mm feed dogs. I generally do garments and quilting but am wondering if I am making the proper decision since I want to be more accurate in my quilting precision. Is it possible to get perfect 1/4 inch seams with the 9mm feed dogs?? Do the large feed dogs make it harder to sew garments as well? If not which machine do you suggest? Hubby wants to invest in something I can grow into (embroidery, decorative stitches etc) Thanks a bunch
