I used 5 1/2 by 8 1/2 Crumb cake paper, along with 4 by 5 1/4 Vanilla, 3 3/4 by 5 Marina Mist and 2 1/2 by 3 3/4 watercolor paper.
Stamp your image with Stazon, rather than the regular ink and let it dry for a few minutes.
Once dry, get your ink pad and squeeze it to get some ink on the inside of the top panel. Once you open the inkpad, there should be enough ink on it to start your watercolor adventure. Dab your Aqua Painter inside the ink and place is on the paper in a random motion squeezing water from the Aqua Painter as needed. Here you can see this fun Watercolor technique as demonstrated by Julie Davidson.
Here is another variation of the same card, using the same colors, stamps and ink.
