Also be sure to check out Leah Day's website:

She has a ton of great videos on different designs in free-motion quilting with a domestic machine.
I have quilted on all of my machines, including Singers and Brothers. It takes practice but it can be done! The book "Machine Quilting in Sections" by Marti Michell is another good resource.
