One dip in the dye bath and you have something brand new! Dyeing is as much an art as a science, so don't hesitate to experiment. Give a set of plain white dish towels a colorful upgrade, an old scarf a prettier shade, or a string of wooden beads a beautiful new hue. Try a new technique like shibori, ombre dip-dyeing, batik, or everyone's favorite—tie-dye. Just remember that natural fibers—like cotton, linen, silk, and wool—take dye much better than synthetics do.
