I dyed silk and cotton fabric with avocado skins. It’s a nice peach dye which doesn’t need a mordant. I dried the skins and chopped seeds of two avocados. The chopped avocado seeds become more red after contact with the air. Then I boiled the avocado skins, seeds and water for about one hour. The dye solution becomes reddish brown while boiling.
Then without removing the avocado pits and skins, I boiled the dye with the fabric again for about one hour. Some of the fabric I removed after that from the dye bath, while some of the fabric I left soaking till the next morning.
