I need to make a lrge hand-dyed piece with certain areas dyed different colors than the main body of the garment/fabric. I'm considering using batik to resist the areas I won't be wanting dyed the main colors. Does anyone know if a) say I want to keep really really clean edges between colors, when I wash the wax out of the garment after the main dyeing, if I put wax along the edges of the main-color area where it meets the undyed area to prevent bleeding, will it damage the already dyed area? b) will it damage silk fabric to rewax and rewash some areas several times in the process of getting all the colors I need on the piece?
Because
what I'm trying to reproduce (colored in really roughly and poorly, the pinwheels will be embroidered in various colors) is late 1600's Japanese, to be remotely authentic I'll need to use plant based dyes. Does anyone have any tips for making the dyebath into a slightly more paintable substance? Does anyone know if I can layer indigo and madder to get a good, dark, rich shade of purple? By which I mean dye in the madder, let dry, dye in the indigo, let dry. Overdyeing, I guess.
Expect many pictures of the proccess and final product. Right now I'm in the research stage, but that will probably give way to the "testing materials and techniques" stage soon.
