I love to find a stamp (Tag is by Art Impressions) that has sufficient white space for a Zentangle. I used a background of Basic Grey's "Little Black Dress" paper and two black & white ribbons for embellishment. I drew the Zentangles inside the tag and added the red to the "Poke-Root" and the shadowing with Copics. The tag was cut out and floated with foam tape.
The inside of the card states simply: "Just dropping you a line...".
