I like to use #10 crochet thread that comes in a big ball. Much cheaper than embroidery thread. I also use Fray Check (the kind that stays soft) on each knot. I can't stand to waste my precious embroidery thread on ties. lol I have almost every color DMC makes - yes in numerical order in one two sided tackle box and two more compartment boxes. I feel the same way about my thread that most of you do about fabric.
