My only double page layout from all these kits... not that you couldn't do plenty of doubles, but just that I default to single pages most of the time. Probably because double require me to clean my desk before I start scrapping.
I love the orange, green and red combination and used it more than once. For the cameras, I added orange ink to the patterned paper then stamped the grid on top in a darker orange ink and cut out the shapes when the paper was dry. Yes, I just admitted to having at least two shades of orange ink. Orange, of all things. So don't worry if you have multiple shades in colours you rarely use. We can form a club.
