This yarn is unbreakable! Really! Well, with your bare hands. Under enough pressure it will break. Physics and stuff. Disclaimer over, this is my favorite method for spinning yarns to knit or crochet into market bags. Join me to corespin an art batt and locks on a special core that you can find at your local craft or hardware store! Try adding wire to this yarn to create a unique sculptable unbreakable yarn that is fun to use in freeform weavings.
