third loop of half double crochet

Ever wondered what the mysterious third loop is? Or perhaps you heard of the “extra” or “third back” loop and never knew why it’s useful. Well, the third back loop of a half double crochet is just that, a third loop that is situated at the back of the stitch. It’s important mainly because when working into this loop, the regular front and back loops of the half double crochet stitch remain empty, creating a beautiful braided look.
