I didn’t elaborate on willow as a natural dye material in the handout. People in the class had already seen naturally dyed yarns I had taken for show and tell. And you’ve seen plenty of posts here on that topic.
The instructor for that ethnobotany course, Stephanie Aleman, will teach another continuing ed course in the spring. It’s called Appreciating the Ephemeral Flora of Wisconsin. It’s six sessions in April and early May, and will include field trips. I know where she was planning to take the class and would really, really like to see that wonderful place with her as a guide. But things are still too up in the air for me to put something else on my calendar. Yet.
But if you’re in central Wisconsin, you might check it out. It was well worth the 2-1/2 hour round trip drive every week last fall!
