Well, this site has inspired me to want to give FMQ a try. I went on-line to order a presser foot for my Singer Futura CE-150 (low shank/snap on) and found too many choices! There were plastic ones with 1/4 and 1/2" markings, metal circles, metal open circles, big foot, some have the springy-thingy on top, some don't...I'm confused! What serves you the best? Have you had any problems with the plastic breaking? Thanks in advance for your help!
