Dearest Jennifer,
I have a black 50%Viscose, 30% Cotton, 17% Nylon, and 3% Spandex sweater that is now looking a little faded. What dye do you recommend I use to dye it back to black @ home? Also I live in the Los Angeles area do you know of any local Fabric Stores where I can purchase this dye from?
Thank You,
Monica

Dearest Monica,
I would try the industrial dyes from www.dharmatrading.com. This is what I use to over dye black things that have faded. Caveat, you must be willing to put your sweater in the washing machine on hot.
have fun,
Jennifer
