Brew tea in by pouring boiling water over the tea bags in a large bowl. Let the water cool down to a warm temperature and remove the tea bags. Next, run the piece of fabric or clothing under warm water. Squeeze out the excess water and immerse the fabric in the tea. Stir the fabric with a wooden spoon to avoid wrinkling and to saturate every part of the fabric with tea. If the fabric wrinkles, it will result in odd staining patterns on the fabric. Soak the fabric for a few hours, or until it reaches a desired color. When the fabric appears ready, remove it from the tea bath and rinse it in a solution of warm water mixed with a dab of dish soap.
