I've got a large 100% wool blanket, but it's an awful pale green colour; as it's a civi one it hasn't been felted at all. My idea is to put it in the washing machine with some van dyke crystalls and wash the dye through it at 40 degrees.............will this work? Does anybody know if I'd need to fix the dye in some way afterwards? And would this wash-through at 40 C be enough felting?..................Any advice or input would be greatly appreciated! atb mac
