Here is a link to one of the best free motion sites that I think that is out there. She does it all on a domestic machine. This year she just started doing a new kind of tutorial where you can go right along with her. There is alot to her site so check it all out. There are tons of designs and ideas as to how to do things. Good luck on quilting. It's good that you have your mom there to help you out. Both of these links are for the same person; the first one is for her latest lessons.
