I used 1" netting that I had around the house (like fishnet) for the base, then I went to Joan Fabrics and bought 2 yards of each color of predied burlap. Dark Brown, Light Brown, and Green. Then, I dethreaded the burlap, thread by thread, this took a LONG time. I just did it while watching movies, and listening to music. After a good while, I had the burlap sheets broken down into their respective threads.
Then I mixed the different color strands by hand into groups of 4-7 strands. And tied them onto the netting. This took a long time but it only cost me 17$ for the all the burlap. Then of course when you get to the place you are going to play at, cut and attach small branches and leaves to match the scenery.
I play in a deserty area, and attached some sage, seemed to do the trick for me.
I am hidden and aiming at the camera in this one.
So to answer your question, 17$ for burlap for a full ghillie, and all the colors you basically need, is a hard price to argue with. Just depends how many man hours you are willing to put in. That alone might be the cost. That still leaves you to search for netting, some suggest the volleyball net, but I like 1" squares, 4"x4" just seems too big for my tastes. Good luck.
