you said it is a crazy quilt? does it have embellishments? like buttons or items you would not want to run over with your machine? you asked about quilting it from the back? why would you be thinking about this? is the picture of the front or back? assuming it the front, are all of the blocks like this one? if so i would just load it up and do an all over meandering quilting pattern, possibly with loop-d-loops, stars, hearts, flowers?
