My senior independent study organism- a lichen- turned the water yellow when soaked for cell studies. This was in 1964. That started me in learning about natural dyes which led to weaving then to spinning and on and on.
Now I am the lucky person who has many 'hobbies' I love to do. I go to sleep thinking "now tomorrow..." and wake up thinking "Oh great- I can do...today".
How wonderful is that?
