last night i boiled 5 chesnuts to make a recipe and noticed the water had a lot of color.miss frugal here saved it and this morning i dyed some rough silk which had been previously mordanted in alum.
soft simmer for an hour and the color is simply amazing! the silk is still sitting in the dye pot waiting/hoping for the color matter to exhaust. will post photos when the yarn's ready.
best,
