So I'm going on my first hammocking trip, and I'm going as cheaply as I can. I'm just now graduating with no job, and thought now would be a good time to take a 3 day trip backpacking while waiting to hear back from some jobs I applied for. So I essentially have no budget for this trip, other than the $20 I spent on my hammock. I keep reading about sewing tie off's for walmart tarps, because the grommet's will fail. If I'm most likely only going to be using this tarp on this one trip, how necessary is it for me to sew a tie off? I'm terrible at diy, and would prefer to avoid sewing a tarp.
