I have always been a 12x12 layout kind of girl. I did some experimenting with Project Life and pocket pages. I like the pockets for certain pictures and layouts, but there is just something special about a fully "crafted" layout. I love the way it highlights certain moments in time and in space.
So, when I started my baby's album a used a combination of sizes and styles of pages. And, one style I wanted to try was an 8.5x11 layout. I still use 12x12 papers, I just trim them down. While it is only a few inches different, it makes a huge change in the look of a layout!
The first time, I was also surprised about how much less space their was to embellish... a blessing and a curse. I have to be really intentional with what I use and the space it takes up. But, I love the way it looks for a special page.
