Looking at your photos, start by picking a theme for your page. The theme can relate to the events, people, or places in your photos. They can be one-work themes like "Love" or "Joy".
Let your creative juices flow and you'll find yourself with a solid start to an impressive layout design.
NOTE: Most often, when I refer to a scrapbook "page" , I am meaning a 2-page layout. While there are a few benefits to using the occasional 1-page layout (eg. at the beginning of an album or to mark a separation within an album), I always recommend a 2-page layout for the sake of consistency, flow, and overal visual appeal.
