I did not include detailed instructions on sewing or whipping the ends or waterproofing the tarp. There are wonderful instructables by other authors that include these needs in great detail.
I would strongly recommend using elastic shock cord for the side tie outs on the hammock and for four points on the tarp.
NOTE:I used 550 para cord. I have read this is not a good solution for this. I double the cord and I think at 6' @ 170lbs I should be ok. It is strongly recommended to use something much more sturdy like 1000lb tested cord or mule tape which is rated in the thousands of lbs.
As always use extreme caution when constructing anything that will be suspending you or anything that is flammable or vapor horrific.
I based this design very roughly off of several retail designs. My favorite being the Hennessy Hammock Tent. It is one of the most beautiful and elegantly refined products on the market.
