I agree with Bree...for a child's quilt, it really should be quilted much closer than 10 inches. I just gifted a Warm Wishes quilt to our new nephew which I simply used my walking foot to do cross hatching about 2 inches apart. You could use light color thread on top and dark blue in your bobbin. I would post a picture but I haven't figured out how to do it from my new Ipad (sigh).
