I used a stencil and the technique "monoprinting" to achieve the background. So much fun! You start by smooshing your chosen inks on your stencil, you spray it with water just til the ink beads up. Then you carefully turn the stencil around and place it on your watercolor cardstock and press. I put a paper towel on top as well so if any water comes ozing out through the stencil, it's caught by the paper towel. Then lift the stencil up and let dry. You never get the same result twice so it's always exciting to see what you get.
I finished the card off by die cutting them with a Hero Arts rectangle die. I also cut a blue mat with one size larger die and then mounted on a white card base. The sentiments are from Lawn Fawn, die cut in black card stock (3 layers) and then with some Wink of Stella on top.
