I found that if you do straight stitch with the walking foot for the inside of the quilt then do a fancy free motion on the border it is great practice.
That way the bulk of the quilt is always to the left of your machine.
Much easier to handle.
The first design I used was a simple leaf continuous line border.
Another is hearts continuous line. Both available at Joanns.
You will have to learn to stretch or subtract from the design to make it fit.
I like the dissapearing ink pen to draw the design on with.
Be sure to use thread that matchs the fabric or invisible thread, that way the design is not real visible for mistakes.
I saw a hint in a book about using a backing fabric that has a big design on it that you can stitch around for free motion from the back of the quilt.
Great idea, now to find just the right fabric.
