Une tasse blanche avec un dessin graphique

1   Use a tape measure and measure the precise distance (15 mm) between the vertical lines. Mark with a pencil.

2   Use a ruler and draw with a black glass and porcelain marker. Leave to dry. A tip: The mug with graphics is dishwasher safe at a low temperature, when it is fixed for 90 min. in a household oven at 160° C.
