also, if you cant' find what you need from Nancy's try Clotilde's they carry feet too.
i was pretty upset when i took a class and was told i had to have a walking foot in order to take the class; i had just recently purchased my Viking Designer one...so i called the shop about the foot, they said, of course they had one and would take the order over the phone and send it to me...THEY CHARGED $89 for that walking foot!!! then my daughter comes in having just bought one for her maching (from Nancy's...$12.95!!!) exact same foot!!! i tried to return the one i bought but they would not let me, so i keep it visible at all times...a reminder that i should ALWAYS shop around, and NEVER just buy from the dealer, because they tell you you should. and the worst thing about it, i used it once in a 2 hour class and have never used it since, it has sat there in it's box, with the price tag on it for the past 5 years...collecting dust.
