Depending on your style, a layout can be full with as many pictures and as much memorabilia as you like (as long as it still looks good and flows!), or as simple as you choose with as little as one or two pictures.
Many Scrapbookers will make their pages very full of embelishment and only feature one picture. I prefer to tell a story in my books, and like to feature an entire event in only a few layouts if possible.
Whatever style you are, I will work with you to preserve your memories how you would like to see them. Check out some of my other layouts for more ideas!
