On my "old" Viking I have every foot that was available at the time...bought them little by little and yes, used them all....and still do.....like ruffler, cording, walking(of course). On newer BL, just use what came with it, although I did buy additional 1/4" and 1/4" with flange, and really dislike both of them.........the attachments for the new machine are as high priced as the machines are! Can you tell I still love my " old lady"!
