I finally went and threw a DIY hammock together today out of red Joann's ripstop. Full fabric width of 60" and 10.6' long.
I went with the stretch side, but just used cord locks instead of buttonholes/ grosgrain tiedowns. I put cord locks on both ends of each shock cord, and put a small knot outside of the locks. If need be, I can remove the extra cord locks if one on another piece of gear breaks in the field.
Works great! Thanks for the inspiration and walk through. Hope to see you at the Sods again this spring, Knotty!
