The advice I can give you is this:
*It is going to take practice.
*Make sure you can lower or cover your feed dogs.
*Have a walking foot and a darning foot.
*You HAVE to have a machine with enough throat space. For my birthday my DH bought me a new machine with 9 inches of throat space. SO EASY TO QUILT NOW!!
*Buy some good books about machine quilting. I love my books.
Good luck with it. I can stiple and meander, and am learning free motion with designs and such. The hardest for me is relaxing my shoulders..and getting the stitch speed/hand movement speed in sync.
