Rabbit's post on reviving old garments reminded me that I have an old black maxi skirt that is looking tired and could use a color refresh. The material seems to still be in good condition; the color is just faded. I've never done anything like this so thought I would ask my fellow fabbers.

What products do you use? Where do you get them? Are they nasty chemicals (I can get bad headaches from chemical sensitivities)? What equipment do you need?

Thanks!
