I made Charlie some play silks a few days ago. So easy! I put each scarf that I bought on Dharma Trading Company (36") in a quart sized mason jar filled with water, about 1/8 cup of white vinegar and food coloring (as much as it took to reach the color I wanted). I then put the mason jars in a water bath about 3" deep and boiled them in the water bath for 15 minutes. Rinse until water runs clear and hang to dry. You can also dye these with Kool Aid, but I could not find any single batch packs anywhere.
