How big is the quilt you are doing? If it is quite small, you might be able to do that pattern with a walking foot, but it would involve far more manipulation of the quilt than I would want to do. If it's larger than a twin, I would definitely do free motion.
I personally am not a fan of that fabric except as a tool to learn how to free motion. The problem I see is that since you are working from the back, your quilting does not relate to the pieced work of the quilt top (unless you have been very clever and very fussy about lining everything up). I like to see the quilting stitch design relate to the top -- not just be a design that is plonked down.
What I would probably do with that fabric is make a whole cloth sandwich in pretty fabric, and use the project to perfect my free motion skills, then do a quilt top (with the top upwards) with free motion design similar to the curves and swoops I had learned from the practice work.
