I walking foot will help it feed better, make sure you are set up right for it, do a few practice sandwiches to practice on, that way you can also adjust your tension and other things if you need to without having to pick it out if it isn't correct. and if you are still having problems, you can post pictures of what it looks like and the odds are someone will be able to tell you what you need to do, so don't forget to check your needle and thread before starting,
