I challenge you to use circles as a dominant theme on your layout.
For this layout, I used a circle punch to cut a whole bunch of circles from coordinating patterned paper, then arranged them in a column on my layout. I matted my photos on black cardstock to create contrast from the background, to create a unified focal point, and to coordinate with the letters I chose.

Supplies used for this layout:
Scenic Route background paper
American Crafts letter stickers
Prima patterned paper
Bazzill Cardstock
