I've put together a couple different ones.
I used the Army issue hammock for the webbing base.
Cut up strips of burlaps (burlap bothers people with allergies) and overhand knot the strips to the hammock webbing. You can use 550 cord for additional tie down points to yourself. You don't have to fray the strips because the burlap frays on it's own with use. The more you use the suit the better it becomes (crawl on the ground, river crossing, rain, sweat).
When you cut your webbing go bigger than you think you need because the more strips you tie into the webbing the smaller your overall size of the webbing becomes.
I crawled up and out of the hill for the below picture.
