If you don't like stickers, you can buy stamps with the same mermaid in the Mermaid Shelfie set.
Here is the card I used with my stickers. I colored the whole sheet with Prismacolor pencils while watching tv, one of my favorite things to do. The background was made with Hero Arts watercolor ink bottles. I dripped the blue and yellow inks onto a sheet of Bristol paper and then after it dried, I stamped and heat embossed the Hero Arts Starry Night Brushstroke background stamp. I think it looks a little like waves.
In this close-up, you can see the bubbles I made with the Nuvo clear drops. I love those things! The clear ones are cool, the colored ones are pretty, the glittery ones are fab and the glow-in-the-dark are super fun.
