-old normal loose fitting close that you don't care to ruin and are not brightly colored
-black brown and dark green clothing dye
-lots of old white rags
This is very easy to do, but very time consuming. Take the rags and dye an equal amount each color. Make sure the colors resemble the natural colors where you play. For example you wouldn't want a bright green color if there are no leaves on the trees. Cut the rags up into 2 inch by 1 inch strips. Put all the strips into a big pile and mix them up so you will get an equal amount of each color spread out evenly. Sew the colored pieces until it covers up your old clothing.
