The nice thing about Simple Stories' collections is that they give you building blocks for your layouts. They have several papers in each line that are blocks of 4x6 patterns, perfect for mixing in with photos.
Here I used one of those blocks in a grouping with three vertical 4x6 photos. To the left is a group of horizontal 4x6 photos. I used pieces of two other papers to bookend my large photo block. The piece of calendar paper is great for journaling.
