My friends and I recently when snorkeling in an underwater cave here in Florida known as Devil's Den! Such a fun experience!
I used the sketch from Colorful Creations to complete this layout. Check out their sketch here: http://anothercolorfulcreation.blogspot.com/
This layout included stitching, a slight layer of gesso, spraying and doodling.
I'm also entering this in the Girls Only Challenge this month and Creative Embellishment's picture challenge. Creative Embellishments had a great nautical themed inspiration photo and I had some nautical themed pictures to scrap so it worked perfectly!
