The thread on part one of the series is here.
Part two of the series spends a remarkable 15+ minutes talking about making an endcap! Almost as long as it takes to actually make it and sew it in. Closes with the webbing being sewn in, so the video ends with a completed hammock body, sans suspension or bugnet....so there'll be more...
Note in passing...if you don't intend to sew a bugnet to the top of the endcap, then
a different type of endcap such as the one demonstrated by hangnout is bound to be easier.
There are lots of ways of skinning the endcap cat.
