Place the napkin right side down on the table.
Fold the napkin in half diagonally.
Starting at the folded edge, roll the napkin three-fourths of the way up.
Then turn the napkin over so the roll is facedown on the table.
Choose one end of the napkin, and begin rolling sideways along the existing rolled edge.
When you finish rolling the napkin, tuck in the end.
Turn the rosette facedown, and pull the two corners remaining outside the roll away from each other to create leaves.
Turn the rosette over, place in a the tea cup, and enjoy.
