Hammock: Sew a channel in the ends. That gives you the flexibilty to whip or gather the ends.
Suspension: Whoopies are actually quite easy to make once you ahve the right tool. Whether you buy a proper fid, use guitar string, carpet needle, floral wire, or whatever you just don't rush it. Work it slow and smooth and you'll be surprised how easy it actually is to do.
Slow is smooth and smooth is fast.
- If you're attaching the bugnet to the hammock, have someone outside pin it to the hammock while you're in the sweet spot.
- If removable, then check all the designs here and find the one you like the best.
Tarp: The Winter Dream sounds about what you're looking for.
Good luck on your projects and I hope to see pics of them soon.
