Greetings!

I am a devoted tea drinker, particularly of Chinese and Taiwanese green
and oolong teas. I am currently writing a book on tea, with one
chapter devoted to suggested uses for used/spent tea leaves (tea bags).
I have already "rounded up the usual suspects" -- that is, I know all
about using used/spent tea leaves as compost, to remove odors, as a
hair rinse, to clean floors/carpet, to relieve stings, to freshen puffy
eyes, as a dye, etc. What I am looking for are the more unusual uses
-- for example:

-- anybody know of using the leaves as feed for certain animals?
-- anybody know of any recipes using the leftover leaves in BAKING?
-- anybody use the leaves as material for a certain hobby?

Does anybody have any unusual uses for their leftover tea leaves?
Any/all information will be greatly appreciated.

Thanking you in advance!
