Whenever I eat an avocado I wash and dry the pit and put it in a plastic bag in the freezer. Recently I took out some of my pits, thawed them, put them in a thick plastic bag and smashed them with a mallet. I soaked them in a large jar for 10 days, stirring daily. The liquid started out a clear orangey red as shown in the photo but gradually turned to a cloudy apricot colour.
I cooked the pits for a couple of hours and then let them soak overnight before adding the fibre. I heated the dyebath to just below a simmer, held it there for an hour and then let everthing cool in the dyebath overnight. I was able to do several repeat dyeings. The wool and silk dyed a beautiful soft apricot with the cotton becoming pale apricot.
Broom is considered a pesky invasive plant here in coastal British Columbia. However, it does have beautiful yellow flowers. I gathered a large bowl of flowers, tore them up a bit and soaked them and the wool in water overnight. The next day I cooked the dyebath for an hour, being careful not to let it reach a simmer. I let the wool soak for several hours and then removed it and let it sit without rinsing. The next morning I rinsed the wool and left half as it was and the other half I overdyed with indigo to get a beautiful green.
Horsetail is another pesky plant here. I need go no further than my garden to gather some! I picked enough for a strong dyebath (about twice the weight of plant to fibre), cut it up and soaked it in water overnight. The next day I cooked it for a couple of hours and let it sit overnight before dyeing the wool the next day. I overdyed half the wool with indigo to get a lovely mossy green.
Myrobalan is a tropical nut which can be used as a tannin mordant or in larger quantities as a yellow dye. I bought mine in powdered form from Maiwa. The green silk is the result of overdyeing with indigo.
Early in spring I had to prune the end of a small branch off my red maple tree. This is the result of my dyeing. The bright pinky silk fabric in the right bottom is from the first bath and the other fabric is from exhaust baths. The smokey teal and dark forest green are from overdyeing with indigo. I love having an indigo vat for overdyeing! I'm going to do another dyeing at some point to see what colour I'll get because the leaves on the tree have turned from a bright red in early spring to a deeper winey red and may give a somewhat different colour.
