HELP!!! i just bought some very nice raw silk from my local joanne's and i need to dye it. the only color they had was a light red/pink and i was hoping i could bleach it and dye it to an off white or gray like obi-wan's aotc tunic. anyone know how i could go about doing this? i tried taking a small piece and soaking it in a sinkful of cold water and clorox bleack for about 20 mins, but it seemed to have no effect.
