I think this is great advise but I have a question. I have a 15-91 in a cabinet that I want to learn FMQ on. I am thinking of taking a class but I really can't see lugging that whole thing to class. I wasn't even able to get it into the house without some help. I have a "newer" basic singer (1999) but its not that great for quilting as the dogs don't drop but can be covered. The LQS rents machines for people if they want and I was thinking of doing just that.
I do agree wholeheartedly that one needs to come to class prepared for it.
