This seems a good of a place as any to mention that I’ve got an Etsy shop where I sell two different hand screenprinted Tolkien-based shirts.
The first is a green Fool of a Took tshirt:
Are you a fool of a Took? Do you know someone who is? Well, this is the shirt for you! And you can pick it up on my Etsy shop.
The other shirt is admittedly not for everybody.
You can pick this up here. The green, solvent-free, water based ink is hand screen printed upon both sides of a 100% organic and unbleached cotton shirt.
Tolkien was no stranger to vegetarian characters. The fierce Beorn and his kin all abstained from eating meat. But it’s possible that at least one clan of Elves was also vegetarian (though Tolkien does not say so one way or the other).
Here’s a bit about the Green-elves:
“Now the Green-elves of Ossiriand were troubled by the coming of Men, and when they heard that a lord of the Eldar from over the Sea was among them they sent messengers to Felagund. ‘Lord,’ they said, ‘if you have power over these newcomers, bid them return by the ways that they came, or else to go forward. For we desire no strangers in this land to break the peace in which we live. And these folks are hewers of trees and hunters of beasts; therefore we are their unfriends, and if they will not depart we shall afflict them in all ways that we can.'”
-Silmarillion, Chapter 17, Of the Coming of Men into the West.
I’ve also got a handful of other shirts in my shop. Check them out if you like.
