Googling comes up with seven, heaven, leaven. We're not making bread, so that one is out. Heaven is tricky to use and not offend. Seven isn't very helpful either...does the slogan have to rhyme? What about taking Disney's "Let the Memories Begin" and adding a scrapping tag? Like
"Letting the Memories Begin, and Have the Scrapbook to Prove It"
I'm bad at these things.
