I think your quilt is absolutely stunning! You did everything perfectly. I can't stop looking at it...it is just so lovely. It obviously took a lot of preparation and work to complete this top and now that the top is done you must be admiring your work...I know I would be if I had accomplished it. I think your thought of stippling is right-on. It is going to be time consuming to do the stippling around all those pieces, but oh, so worth it.
If you could enter it in some show I am sure you would get a blue ribbon!
