All of the things mentioned can be used to tie a quilt. It just depends on the look you want. Yarn is more obvious than the floss, crochet thread, or perle cotton. It also requires a larger needle and is harder to pull through. That's why I use floss or perle cotton. Most of my crochet thread is white so have not used that. I also use a curved upholstery needle. It will go down and back up easier than a straight needle. Tying a quilt is a great traditional way to quickly finish a quilt.
