I have more feet than I know what to do with. I have three Bernina machines as well as a B serger and seperate embroidery machine. I worked for more than a year for a Bernina dealer who made her bread and butter doing alterations and custom sewing. I learned to use all of the feet. I also actually took a formal class in Heirloom sewing. I made a beautiful Christening dress which I may never have a grandchild to wear. Because of that class I purchased all of the pintuck feet. They and the cording feet are fun to use.
