Creative. Our church started a program called Peter Pebbles where adults paint on rocks including a Bible verse, and when the kids memorize a section of the Bible they can pick one out and take it home to keep. I started painting them in 2007, starting with space paintings since that's my primary subject. After a few I thought that since these are for kids I'll try a cartoon. After I did that then all of my friends wanted one too, so I've been painting them ever since, current count as of 3/19/2008 is 181 rocks. I think I'll start counting them by weight... :-) They always have a Bible verse, so that's my way of spreading the word.
