Hello, Stampers!
Isn't this undersea watercolor gorgeous? I did create the cards shown here, but full credit must be given to Nadine at https://NadineKreativ.de. Nadine is a talented Stampin' Up! demo in Germany. You can find her on Instagram, Pinterest and YouTube. I've shown a very similar version below - the only difference being that I spritzed it with Lindy's Magicals powder (mixed with water) in Hydrangea Blue.
Keep reading for the instructions and supplies - fewer than you might think!
