Copycat....I will link you to the video.
Basically, you trace the Panto onto the back of the backing (So, you have to be able to see through it. ), sandwich your quilt and then just follow the panto, quilting the back. Be sure you have whatever thread you want to show up on the front in your bobbin. I didn't mind it although all the tracing was boring. I traced with a blue washable pen.
