In reading the thread on a neat sheet that was provided, there are a couple of things that I would be hesitant on using a "neat sheet".
1. the finished weight.
2. Do you plan on total coverage like a UQP? The coverage is total,,up to the edges of the hammock all the way around a bridge for blocking wind and containing heat even tho the material of my UQP is breathable. As well as the spray from blowing rain. Total coverage on the bridge, and I would think on a gathered end hammock as well. The neat sheet would only cover so much and give off heat loss to some extent I am thinking. However, maybe somebody with a "neat sheet" can chime in and help us out here.
