I've become quite the fan of an inspirational challenge blog called Scrap Africa. It's a little different, with a mix of sketches and challenges and a lot of lovely inspiration. The design team do some outstanding work and most seem to realise that scrapbooking isn't always about throwing as much product on a page as you can. To me scrapbooking has always been more about what I want to convey. I like to think about the story I am trying to tell and the photograph(s) I am showcasing.
The current challenge is to use postage stamps on your layout.
