Oh well. I was just talking with my mom about my playsilks. Her Bachelor's is in Textiles. I called her to ask if she thought I could redye the playsilks I made tonight. Maybe it would give them a more even color. She wasn't so sure it would work. Seems the vinegar might have already set the color in the fabric and not allow it to take in any more color. She said I could try it again and see what happened. I might. For future endeavors she suggested a bigger pot, more water and more Kool Aid packets. She said the generic Kool Aid most likely used a different/cheaper color agent which made it harder for the fabric to soak it up.
Something else I forgot to mention. When I used the generic Kool Aid, my hands were stained something horrible. When I used the Kool Aid brand tonight, not a drop of color on me. I was afraid of looking like a rainbow at pre-school pick up tomorrow!
