The Knot in the Handkerchief [Uzel na kapesníku]

A boy makes a knot in his handkerchief to remind himself to repair his leaky faucet. The handkerchief, however, is alive and kicking, and flees from its pocket to explore the outside world. The boy gets distracted by a game of soccer, forgetting the faucet. In the meantime, the handkerchief meets other pieces of fabric that come to life.
