I hadn't actually considered trying to find a similar fabric (it is nice!) but using nylon from a "regular" supplier (Hobby Lobby had a few colors to choose from last time I was there). If it costs $6 a yard, and I need 4 yards of each color, that's $48 + tax) for two hammocks. I've already got a support system.
HE, I had sort of assumed that I would make more of a speer clone, since that's what my first hammocks are. I was just considering a better color combination, as opposed to the stealthy (which I like when not at a campground!) forest green and olive/greyish colors that we currently have.
If I did decide to make more of the HAAB style, I think I would go with something along the lines of a modified style, like what is seen here, when headchange4u added an internal structural ridgeline to the Warbonnet El Dorado
. I could make something along these lines, then tie my (currently) webbing just below the whipping.
I might be missing something when trying to combine the two designs, but... who knows.
So for a short answer. I am more interested in the dual-color appearance than the style of the ENO. I'd have to try one out to see if it's worth making a more exact copy (I'm sure it is, they seem like great gear!)
