First I did this one. For that magical third color I added some Mike's ribbon that had some Teal in it, then used some Teal in the hats. The card is an A Muse 4 1/4 square that I mounted on a 4 1/4 x 5 1/2 piece of card stock so it will fit in a standard A2 envelope without sliding around.
Then I remembered seeing the penguins used separately, so I stamped them separately (they are too close to just stamp once then punch - too bad!) and followed the same theme - A Muse card on a 4 1/4 x 5 1/2 piece of Olive card stock.
Next I used a different A Muse card and mounted it on Blue Bayou, and used a different Mike's ribbon.
Update 12/23: Thanks for the feedback! Here are versions 4 & 5, one with a blue rectangle and one with green. I tried the green because the blue-on-blue seemed boring. What do you think? Closer?
Update later 12/23: I guess I should have called this a Card Evolution! I had a DUH moment, and decided since I could not make up my mind between Green or Blue, I did both! Gotta layer! Below is my final version.
One final note: The Cuttlebug and I had a little disagreement with the Nestabilities, so this version is straight layers...no scallops. Ah, well. Thanks for all the feedback!
