Enlarge template to desired size on a photocopier; cut out.
Position template inside vessel using tape. With an extra-fine-tip paint pen, trace pattern onto glass. (If you make a mistake, wipe with a damp paper towel while paint is wet.)
To repeat pattern around glass, shift the template inside vessel, and trace again. Let dry.
