Quilting - I love fabric crafts and would love to learn how to quilt.
Grant-writing - I don't know that I'd ever use it, but if I ever decided to volunteer or work for a non-profit it would be something good to have.
Ceramics - I never even thought about wanting to do something like this, except after I saw some of the really neat stuff that Jeff's mom, grandmother, and aunts have made it makes me really want to learn to try it.
Dance - I think I would enjoy taking some sort of dance lessons. Part of me wants to take an adult ballet class, and another part wants to take something like ballroom dancing. Either way something active would be good for me.
CPR - I've taken CPR before and at one time was certified, but I would like to get re-certified. This is one I think everyone should have to do!
Latin - I don't know why I can't be interested in something even remotely useful like Spanish, but I want to learn Latin.
Cooking - I think it would be fun to take a formal cooking or baking class, especially in ethnic cuisine that I probably wouldn't learn how to make otherwise.
What are some classes you want to take or things you want to learn to do? I'm all about being class buddies!
