This is not my video, but when I got my tarp I was having a little trouble trying to figure out which kind of knots to tie off the tarp to the stakes. In my search I came across this video, and it has helped me out a lot. I now use the adjustable knot that he uses in the video to tie my tarp down to my stakes. I have even used the knot to tie off the ridgeline on the tarp to trees. It is a great knot, as is the other knots that he demonstrates in the video.
However, now the knot has been challenged with the MLD LineLocks. These little locks are light-weight and effective. I will get some different stakes to use with them, but I am happy knowing that I will always have a back-up for the LineLocks because I watched this video.
