with dyeing, natural dyeing that is. my experiments with marigold and avocado turned out beautifully.
i cut some sample swatches from various cotton fabrics, some cotton yarn, and a length of cream wool. first i scoured them in a soapnuts concentrate and soda ash, then using aluminum sulfate as the mordant, i simmered the fabric for an hour, rinsed and left wet. both the marigold and the avocado skins were boiled for a short time in separate pots, petals and skin were removed, and fabric immersed. i simmered the marigold pot for an hour, rinsed and dried the fabric. however, the avocado i let sit for a day, just soaking. the pinks were very light, with a slight brown cast. so i decided i would then simmer them for an hour as well. the pinks developed a much brighter tone. to see the difference; the bundle of wool i removed from the pot before simmering, the brighter segment i left in the pot and simmered. i then removed the fabric, rinsed, and let air dry.
