To really showcase your quilt - I would use white thread for all the background - and use some kind of filler type quilting like stipple or small circles or swirls - then I would try echo quilting around the Queens - use matching thread when quilting the queens - that will make your quilt the focus and not the quilting so much. This is a great quilt by the way - that is a lot of detail work - I would probably be scared to death to quilt it - It looks like a lot of work. I can't wait to see the final finish.
