Thank you so much. I have looked into the Westalee foot. It is good to hear that it does function well. I haven't seen too many reviews out there on it. I was concerned about spending that amount if it was going to be like some of the others that I already have, that don't work well. I will need to decide which machine is going to be my main FMQ machine before I make the purchase. I am deciding between my 301, 201-2, and 15-91. If I choose the 301, then I will need the slant shank. I am still learning about FMQ, so I am trying to make the best choice. Your information about the thread is also noteworthy. I have a lot to think about and a lot of practicing to do. Thank you for taking the time to reply to my post.
