I made a small one to put on top of my head/hat for stalking mulies and black bears.
I took an old mosquito net and cut a 3'x3' square and then started cutting two slits at a time.
In each of these two slits I would combine synthetic threads of tan, green, gray, and dark green to creat a "sage" colored combo.
I made a 2'x1.5' section totally "ghillied". It is loaded in my Badlands 4500 along with my other gear for a 6 day hunt on the Eastern Slope of the Sierra's here in CA.
If I remember I will post up any changes I would make when I am back.
