Billy's channel has some additional vids that make great viewing. They include making a basic leather tumpline, a crooked knife with an antler handle, even a great one on making a functional emergency canoe with a poly tarp! He's also experimented with building a spruce bark canoe and a dugout from a huge Poplar trunk. Awesome stuff! I've subscribed to Billy's channel and look forward to learning more from his wonderful adventures.
A quick thanks to Robin on the CanoeTripping.net forums for directing me to Billy's great YouTube videos.
