A two-sided doorknob hanger that says "Do not disturb!" on one side, and "Please knock" on the other. The do not disturb side has a pink horse with the night sky behind it, while the other side features a herd of unicorns.
To sew, cut out in one piece leaving the two sides attached along the middle line. Fold in half with right sides in and stitch around as close to the edges as possible leaving open the top. Turn right side out and stitch the top closed.
