"Recipe for Coloring Blankets. Make a strong solution of Red Oak Bark, put a table spoonful of Copperas in the solution, boil a few minutes and stir well. Put your white blankets in the solution and boil them half an hour; take them out and soak them in weak ley (lye?) then rinse them well in warm soap suds and hang out to dry. These directions if followed will give a most desirable for an army blanket."
