Postcard Exchange and Learning about the United States

I have discovered an interesting way for the girls to become a little more familiar with the states of the United States.  We are participating in a postcard exchange with other homeschoolers around the country, hoping to collect at least one postcard from each state.  The only problem we have found is that we have had difficulty finding postcards to send.  We decided to make our own.  Madeline and Isabella have been working hard to paint butterflies on cards to be sent out around the country.  Here are some pictures of them painting their cards.

We are doing this through a Yahoo! group.
