For my best friend's wedding, the bridal party has decided to organize a scrapbook as a gift for the happy couple. We're going to ask guests to create and send their own 12x12 page which we'll compile into a book before the wedding. We've chosen the theme of songs and are asking that pages be themed around songs that remind the creators of the bride and groom-to-be.
My question is this: what information do you think we should send to guests to make it easy and fun for them to participate? We've created a flickr account and uploaded a bunch of pictures if people don't have their own, we're also compiling a list of sample songs if people need some inspiration.
We'll also send information about where to purchase scrapbooking supplies.
What information would you include? How would you encourage people who aren't naturally crafty/creative to participate?
