Copperas can be bought at any country-store, and gives a fast nankeen-coloured dye. A beautiful pale green can be made by dipping the nankeen - coloured material into the indigo tub.
In dyeing with vegetable dyes, it will be found that natural stains and dyes can be made from numerous roots, barks, and bog plants. One reason why it is so hard to get recipes of these dyes is because the women who find them out for themselves choose to have a "dog-in-the-manger" attitude toward others working in the same direction. How much better would it be if co-operation in exchanging recipes and experiments could be arranged. It seems so contemptible to be selfish about helping others in the same direction.
Many people find the making of vegetable dyes extremely troublesome, and very much prefer to buy the best article from some one else. Until lately this seemed almost an impossibility, but to-day there are some craft-workers who are willing to share their experience with others. Mrs. Helen Albee, of Pequaket, N.H., has made a number of dyes for the different material for her pulled or Abnakee rugs. These dyes she is willing to sell to other craft-workers for twenty cents an ounce. They are not strictly vegetable dyes, but she has proved their permanent value by years of experience. Miss Charlotte Pendleton, of Laurel, Md., is, I think, the only craft-worker who is really making a business of manufacturing dyes. No amount of sunshine or washing changes the colours; they are most beautiful. They are so concentrated that only a small quantity is needed for a dye bath.
