One of my favourite scrapbooking sites is http://www.scrapbooksetc.com . The site features a lot of "quick collages" layouts. I put together a two page layout spread for my brother's high school graduation. It's very simple, very fast...but I love the overall look! Plus, you get to put together multiple pictures...and the page still looks good and not overdone! Totally awesome! :)
I love the way you KNOW just from looking at one of the pages by itself that something is missing!
The second page is NEEDED to complete the layout. :)
