2eagles...this may sound silly...but try walnut hulls. If you have ever hulled a black walnut, you know how much they stain. I used walnut hulls to redie my old cabela's leafy suit last year, as an experiment. It darkened my suit just like I wanted, without over-darkening. All I did was boil a bunch of walnut hulls outside in a large pot, then through in the camo suit to "cook" for a while. I let the "soup" sit for a few hours to soak up the stain, then took it out to clean up. I would recommend straining out the walnut hulls from the mix before adding the suit, as it was a pain to try to wash off all the hull pieces. As I said, it gave just the desired darkening I wanted. After this, I saw plenty of deer, and even took my first turkey with a bow wearing this suit. The walnuts definately didn't hurt anything, and it didn't cost anything either.
