I have a few machines. With the berninias I use all of the feet at one time or another and like them all. But, for piecing quilts the bernina #57 with the guide is the cat's meow. I do like the other quarter inch foot #37 for sewing because of all the markings on the foot, it makes it easy to know just when to stop and turn on topstitching. Of course I love the walking foot and I think it is a must for quilter's to keep that fabric moving top and bottom evenly. The open toed foot is great to see what you are doing while machine appliquing or embellishing. The teflon foot is great to glide over problem fabric too. Gee .. I am starting to sound like an ad.. Sorry.
