Cereal box globes for Earth Day

I didn't plan well enough ahead of time to do anything particularly special for this year's Earth Day, but I figure a little recycling project and a reminder on taking care of God's Earth is good for us. Luckily, caring for our home is something we can practice every day. If you're looking for some tips on "going green," as we tend to call it these days, this article at Simple Mom may be a good place to start.
The instructions for these globes can be found here at Martha Stewart. Great for old greeting/holiday cards.
Happy Earth Day! If you feel like sharing how you celebrated today, I'd love to hear about it and be inspired. Thanks!
