I have the material for my hammock, but not the bugnet part of it. I have read most of the threads and watched the videos too. Do most "DIY hangers" sew the zipper or the velcro on before gathering the ends? It seems like it would be easier before? Unless there is an advantage to doing it when the fabric is tied off?

Is it possible to find a 2 way seperating zipper that both ends zip toward the middle? The ones I have seen allow the ends to seperate while the pull is in the middle. like a jacket does.
I saw one picture of this type of setup, but the zipper sites don't seem to show this.
