I recently joined a Giveaway group on 20SomethingBloggers. One of the giveaways was from a very cool blog called Life 2.0 (http://catherineslife20.wordpress.com/). Her friend Julie is giving away one free ring from her Etsy site to a lucky winner. The contest ends August 7th. The rings are SUPER cute, I am very partial to the shell one (obviously, since I'm such a beach psycho) :P.
If you want to enter to win, you just have to visit Life 2.0 and follow Catherine's directions in the post titled "Giveaway!"
Good luck! :)
