The official explanation from Wickapedia is:-
Scrapbooking is a method for preserving personal and family history in the form of photographs, printed media, and memorabilia contained in decorated albums, or scrapbooks.
But I thought it would be easier to show everyone some pictures from my own 12" x 12" albums. If you click on the pictures they will pop up bigger.
Two of these layouts were published in a Scrapbooking magazine. The 3rd Layout down of Ben and Harry in Sepia and the one of the boys dressed in Camouflage.
I've taken some more pictures of other layouts and I'll share them with you later.
