Great card to duplicate and use for various occasions!
I used Night of Navy, Mint Macaron and Very Vanilla cardstock. For a little pop, I used Calypso Coral for one of the fish and rhinestone jewels for the eyes. I ran the Mint Macaron cardstock through the Big Shot using the Seaside Textured Embossing Folder (#14148) after stamping the sentiment then used the 2 1/2″ circle punch. Add a dimensional in each corner to lift it off the Very Vanilla cardstock.
Stamp set : Seaside Shore available in Wood (#141622) or Clear Mount (#141625)
Hope your day goes swimmingly!
