I used both sides of the Kaiser Craft Sea Grass patterned paper. I placed the Sea Grass paper as a mat on the card base first and then cut out the Jaded Blossom Scallop Oval through both. I printed the sentiment on a piece of vellum and adhered it to the inside. Then I added the die cuts from Jaded Blossom Tropical Dies, some sequins, and the adorable Mermaid Samantha from the Digital Delights by Louby Loo store. I colored her using Copic Markers and added sparkle with my Wink of Stella brush glitter pens.
This gives you a better look at the vellum window. I covered it with a piece of coordinating card stock with the oval cut out so you can't see where I adhered it to the inside cover.
