Invite your friends too. They might just wait for an opportunity to try digital scrapbooking, and don’t worry, there will be very little fluff so you won’t need extra supplies (although you can always use them if you have some).
Do you know photographers? It might be a great way for them to showcase all those thousands of photos they take (ok they might not fit a thousand photo in the 7 layouts but they can get a lot of ideas).
Remember, the more participants we have, the more ideas and inspiration we each get!
