Puget Sound Mycological Society to learn more about mushroom identification. The whole class was fascinating and now have a better understanding of the processes one must go through to identify a mushroom. The participants brought in various mushrooms to ID. I spotted a grand Phaeolus schweinitzii - a "Dyer's Polypore"! I asked the student who brought it in if I could take it home at the end of class and she agreed. (Thank you!)
Upon returning home I promptly got out my large dyeing pot, chopped the mushroom, covered it with water and set it to simmer for about a half hour. I wish I would have weighed it. I'm guessing it was about 5 lbs. I added some ammonia and used a tin mordant and got the very orange skein dyed in about 1/2 an hour. I had so much dye material left I grabbed by little sample skeins and began adjusting the pH and the mordants. The skeins that turned out yellow had either no mordant (other than the residual tin floating around) or a pre-mordant with alum. Then I threw in some iron and my samples started coming out green! Some skeins I dipped in for 2 minutes to get a lighter color and some I left in for 1/2 an hour. It's amazing how many colors you can get from one mushroom!

Mordants are substances that dyers use to adhere dyes to fibers. Typically dyers use alum, copper, tin, tannic acid, or iron, among others. Each of the mordants will have a different effect on the color. A mordant can brighten, dull, or change a color all together. You can add the mordant to the fiber before, during, or after the dyeing process. My mixed mordant experiment goes like this: I would pre-mordant roving, then spin it into singles, then ply together singles that had different mordants. My prediction: if I dip a multi-mordant strand into the dye it should come out with two colors, giving it a barber-pole effect.
Next I did the same procedure with an alum mordant. After all the roving was dry I spun singles then plied the different mordant strands together.
The results were mixed. Some of the color variations were too subtle to notices. Others had the barber-pole effect that I was looking for. The yarn that I'm holding above was made with a tin/alum combination yarn dyed with red onion skins.

Mycopigments.com We tore up a bunch of mushrooms and put them in a pot. Alissa told us about checking the ph to bring out the colors.

Puget Sound Mycological Society with a plan to learn about mushrooms for eating and dyeing. I've been reading and watching youtube videos about mushroom identification. This weekend I attended the annual event that the Puget Sound Mycological Society puts on. There were TOO MANY people there when I went on Saturday so I had a hard time seeing all the displays. How wonderful that the problem was too much interest!

Anthemion. I started it LAST MAY and I'm half way done. This is hands down the longest knitting project I have ever done.
