I'm still pondering and digesting over a week later and likely will be for some time to come. Today, though, the inactivity faded a bit and I found myself outside gathering maple leaves to bundle in a length of dyed linen.
Not sure what the yellow leaves are - birch, perhaps? - but they're from the backyard too. Their scent was pleasing so I'm following India's advice that if it smells good, it is safe to use.
I'll let it brew for a bit and throw in a rusty bit or tea bag, maybe a stone or two even or another handful of leaves for good measure.
For those following the search for Roy G Biv, tomorrow is indigo day. I've got to admit that this one has been hard.
