Color clothes pins by soaking in food coloring. In each jar or container, pour boiling water, a tablespoon of vinegar and food coloring drops and mix well. You can use any combination of drops to make varying colors and shades. I used both traditional food colors and the neon food colors to make about a dozen different colors. Add your clothespins and let them soak for at least an hour.
