Hints: If you plan to use any of these colors on fabrics, you will have to boil the fabric in a fixer or mordant before adding the colors. You can use either 4 tablespoons of potassium alum mixed with 1 tablespoon cream of tartar, or 1 teaspoon of chrome mixed with 1 1/2 teaspoons cream of tartar. To apply mordant to fabric, dissolve the mordant you have chosen in 1 cup of water. Add this mixture to a large pot containing at least 1 gallon of water. Use the above measures of mordant for each 8 ounces of fiber. Add the fabric, making sure there is enough water to cover, and simmer for 1 to 4 hours, depending on the color intensity that you want to achieve. Turn off the heat and let the fabric rest for another 4 hours; rinse, and dry.

Try experimenting with flowers and leafy materials that you can boil for color. Small rocks, berries and twigs yield pretty colors.
