I'm taking Joanne Sharpe's online class "Letter Love" this month. It's a lesson a day for the whole month of February! It's wonderful to wake up each day to a new and colorful and cheerful video from Joanne. There's a Facebook group, a Flickr group, and a Yahoo group for the class too. I'm pretty sure you can join in anytime, and the lessons will remain up indefinitely. If you're interested, you can find Joanne's blog here.
Below are some examples of what I've already done for the class.
