wow! what a cute, creative quilt--love it! I would use black thread in the black and turquoise in the dresden fans. I'd probably do some pretty dense quilting in the black (pebbles, maybe the lines echoing the dresden fans, or even straight lines going horizontally --although you'd probably have too many stop/starts with that, maybe feathers or scrolls, or even McTavishing) so that the fans would really pop. I'd probably do a less dense quilting on them--maybe just ditching or wavy lines about 1/2 inside the rickrack following the fans. Please post a picture once you get it quilted.
