We went primitive tent camping with the Cub Scouts the weekend after Thanksgiving and I took a zillion photos. I did this simple two page layout and was able to fit 18 photos on the spread by cutting the photos into circles.
Lately one of my favorite scrapbooking tools is my set of die cut circles. I have been using my circle dies so much that I have been keeping them in a small lotus bowl on my scrapbooking desk along with my QuicKutz Revolution - I am not sure they are still selling that model, so I have linked the QuicKutz Epic 6 below. I used the circle dies to cut the photos for the Cub Scout Camping Trip 2 page scrapbook layout. I recommend QuicKutz Cookie Cutter Dies or Spellbinders Nestabilities since both include several sizes.
