Lydia Y- more material alchemy

With all the beautiful fall leaves still around, I couldn't resist...

I just made these for fun, but I think its material alchemy-esque. Its just leaves, tied with thin string.

I wish I could take credit for the idea, but I saw the instructions online (I think on http://www.instructables.com/, but I can't find the actual project) and decided to try it out. Hopefully they'll also dry well!
