This thread delights me! I've been a fan of Tolkien and Middle-earth since I was in highschool, and that... was a long time ago, LOL! I WISH I had to the go-to to make myself a costume, but I'm no good at that sort of thing - I think it's great that you're even considering one! If you do manage to put it together, I'd love it if you could share some pictures!
I just started my weight loss journey at the start of July and I have started my own Walk To challenge as well.. but um, I'm starting with Rivendell!
If for some reason I decide to dress up, I will let you know! I could always dress up as a girly Bilbo.
