When I feel like I've lost my scrapbooking mojo (or even just because it's fun), I always go back to my tried and true layout style:
little photo//little story//little title
It never fails me and I've been making scrapbook pages in this style for years. Makes me happy every time.
Not every page has to have multiple embellishments, not every page has to be a creative masterpiece, not every page has to even have much thought put into it.
A photo and a story on a piece of paper - that's scrapbooking at it's most basic.
