Does anybody use salt as a fixative. I find that very effective - I don't use a recipe but there's one on a dye package/ Whenever I get a new piece of cotton or linen clothing or fabric I test it in really hot water. If it runs I wring it out, make up another hot sink full of salt water, immerse it in that for about 5 minutes, let it sit another 5 minutes, rinse out the salt since it probably is not good to iron fabric with salt in it, let it semi dry, then iron it. This seems to be pretty effective. I bet others have more scientific accurate recipes for salt baths....
