RE: Ghillie suit
GO to the military surplus store and get an OD green flight suit. Get some of the canvas burlap camo, and the screen camo, cut to strips and sew in place. I guess you'll have to make an appropriate headress using one of those screen headgear camo.
If you make it with a large flight suit you can wear clothes underneath in cold weather and less in warm weather.
Have not done it yet, but considering it. Get a baggy suit to leave room to draw your bow.
