I've made this card for 2 card challenges, the Some Odd Girl July sketch challenge and Simon Says Stamp's Wednesday challenge: By the Sea.
I started by stamping the mermaid in blue and then working on the backing papers. I chose a dark blue for the backing, a metallic blue and a Core'dinations blue/green that I ran through a bubble embossing folder and sanded lightly.
For the wave trim I stamped the wave image (from the mermaid set) on white cardstock and then fussy cut around the tops.
The mermaid was coloured in pencil crayon with a green gel pen for the scale detail and white gel pen for the eye dots.
