1. Decide what phrase to write (such as "Chew with your mouth closed," "Use your napkin," or "Use your manners") on the napkin. Cut a strip of paper the length of the napkin. Use a pencil to write the phrase on the paper, adjusting to fit if necessary.
2. Use the paper strip as a guide to write the phrase on each edge of the napkin using fabric markers. Print with neat strokes. At the end of each line in a letter, add a dot in a contrasting color.
