As Brandr settled in Tyrian pulled three leather strands from his bag and carefully matched their ends together. When they were all lined up he carefully folded them as a group over into a loop and then around the "working" ends. After that it was only a matter of pulling the shorter "fixed" end firmly and tightening the knot down. Now his strands matched the one he had given Brandr. "Nah, thank you. Saves me from having to get up and get a snack later," he said with an impish grin. "And the name's Tyrian."

He then placed a rock over the knotted end of his strand bundle much as Brandr had done. When Brandr asked for his approval Tyrian leaned over to look at what he'd done. He nodded and said, "Yep, that's right. Now take the leftmost strand and fold it over the middle one so that it becomes the middle strand." He demonstrated by doing just that; folding the leftmost strand over the middle one.
