You will want to order a custom tarp from Brian to have doors. You will need 4 tie-outs per side and you might want panel pulls added to the sides too for keeping wind from pushing the tarp into your hammock. If going with doors I'd think you'd want something at least 11 or 12 feet long and 10 feet wide. A standard or even deluxe wouldn't be long enough without something like the 2Q/ZQ mod where they actually add material to the tarp.
