I've used crochet thread for tying before (works great...easier than tying with embroidery floss). Someone here showed some kind of tie that looked somewhat like chicken tracks....it was so cute. Also if you tie, use a surgeon's knot....it will stay tied.
Look up surgeon's knot on internet...it will show you how to do it. Also search turkey track on this site and you will find how to do that.
Darling quilt!!!! Dani
