I had a couple of solid grey wool shirts that I dyed. One I tried to just make brown and the other I tried to make brown blotches. I used regular cloth dye stuff from the local store, that needed really hot water. The one I sunk in the tub, squeezed out, and then tacked it to a piece of plywood. The other I tie dyed. The one that I dunked and tacked turned out to be the weirdest shaped thing that was ever made out of cheap wool. I never found the right shaped little kid or midget that it would fit. The tie dyed one got a little more on one sleeve than the other. If you know anyone with a withered right arm that is six inches shorter than his left arm, I have custom wool shirt for him.
