I also have this same model and have quilted over 30 quilts on it (even a few queen size). I really love the space between the needle and body, so much room for rolling up the quilt and passing it thru!!! Have used a few of the quilting stitches but mostly use the one that's row 2, #12, the curves, and just go along the seams.
It works great and really looks good on the quilts! Have fun and enjoy, don't be afraid! And yes, she is a beauty!!
