Thought this addition to my HH Sil Hex tarp may have some interest to some of you. They are made of Sil Nylon, sewn to the seam on the tarp, and secured at the bottom to the opposite corner by a bungee cord/clam-cleat arrangement. When not being used they roll up and tie with simple ribbons attached to the tarp seam. So far it appears they will do a good job of blocking the wind and (hopefully) keeping the rain off of my multi-hundred-dollar-800FP down quilts. And the hammock's occupant. I've also recently added zips to the HH Hyper-Lite bug net and a bungee/Prussik knot tensioner to the tarp's ridge line. Small improvements to keep life simple and more comfortable.
