Thanks, I haven't made it yet, but Risk's site was very helpful. With a relatively new baby at home, I thought I could sub in some "gear time" at home for trail time. As any parent will know, this is definitely not the case...
After looking at the construction of some commercially available ones, plus a few MYOG pages like Risks's, I think I have a basic idea of what I want to do.
I'm tempted to save the ripstop and go with some $1 walmart taffeta (similar to Risk's test hammock) for the first attempt. Someone here mentioned making one out of pants liner material. Might turn out a little lighter (~.5oz yd2 depending on the material), but I'm worried about durability.
Heck, I might have just talked myself back into the ripstop afterall. With limited free time to sew, I might as well make one that I know will work, and then try and find the time to make a lighter one later.
