1.Do a web search for ghillie suits.
2.Pick up a video or two:
--The Invisible Advantage (This is the best one I've seen yet)
--The Art of Camoflage (another good one, but the first one is still best in my opinion)
To strip burlap:
1.cut the bag along the seams(one side and one end).
2.open bag up and fold in thirds so you wind up with three long sections. Cut these three strips apart.
3. From each section, pull threads from middle (I could pull 2, sometimes 3, without having to really pull hard)
You should come out with strings that you would now cut in half before you gather and tie them onto your base (webbing, etc.).
I've heard that one of the most common mistakes is that folks put too much burlap on at first. You can always go back and add easier than you can remove.
