The first embedded video demonstrates the tying of a Sliding Knot Bolo and Neckerchief Slide - both based on the Turks Head Knot. The Bolo requires three pieces of cord from the GWR knot tying event and just one piece for the Neckerchief Slide (along with some PVC pipe).
 
The second video demonstrates the tying of a key chain - based on a Chinse Button Knot. This knot requires a single piece of GWR cord.
