My machine is a Janome and I bought the foot at the dealer. You can check online sources like Nancy's Notions or Clotilde for a generic foot to fit your type of machine. I would first check a machine dealer in your area, so you don't have to pay shipping costs. You need to know if you have a short, long, or slant shaft machine. Most short shank machines, like Kenmore and Janome can use these generic feet. Every customer who brings her machine to the shop to sew seem to have this type of 1/4" foot, so I think they are available for every brand of machine.
Good luck with your search. You will be grateful for the extra precision. Your seams will always match and your points will stay in line. What more could a quilter ask for? :lol:
