For those who don't know mangosteen, it is a tropical fruit, covered by a thick maroon skin and the white pieces inside, is the part that we eat.
I collected all the skins, knowing that they are very rich in tannin, which is of course interesting for natural dyeing.
I dried some of the skins for future use. We had so many though that I thought I needed to find another way of storage because of lack of space.
I first soaked the skins in a bucket with water. Than I boiled the skins to extract even more colour than in the cold water.
I decided to dye my white nuno felted dress in cotton and wool in this dyebath ( after removing the skins) and brought it to the boil. I did not use any mordant. Here is the result, still a bit pale; I might dye over it again later:
I now have stored the remaining liquid in our freezer and will see how that will be going. I hope one day to find a way to get a beautiful maroon out of this. I have put some mangosteen skins in the freezer and want to try the cold technique with them later.
