Stamp a background on your card - using any stamp you'd like - but it must be made up of three different colors. It doesn't have to be fancy or have a dramatic color scheme to meet the requirements.
Because the print was so beautiful, I had to cut the paper where the lines came out best. For the message, I cut out a blue piece of paper with scallop scissors, stamped in the sentiment and inked the edges. Then I smudged the sides with chalk.
Added the 3 colored hearts to complete the card.
