Linda Jo, love that color scheme! It is so soothing.
I went through my stash to find things to inspire me for this challenge and hit pay dirt. The light blue background paper is actually the wrapping from a bar of ocean-scented soap. It has a seashell stamp image and a "postmark" that fit this challenge perfectly. I had printed off a few extra copies of the Bugaboo Mermaid digi and sentiments that I used in the Yellow Submarine Challenge, plus found a cancelled stamp with a wonderful photo of undersea foilage and my card almost created itself. So fun!
