My friend, Rebecca, from View from the Prairie Box, has been doing the DPP for years. I've loved joining her each December because it makes me realize I just have to snap a photo or two of something I'm enjoying, engaged in, watching my children do, whatever, and I have these awesome memories of our Advent and Christmas time to look through.
They don't have to be holiday related at all. Her friend Jenn, made this amazing Blue Room series last year (ack! I can't find it to link up to it, trust me it was epic), and I love following the facebook page to see how hundreds of people, all across the world, are now playing along. It's a pretty neat thing.
