Press a thumb firmly onto the white stamp pad or the paint-loaded sponge, coating it evenly. Too much paint will blur the print; a light, even coat gives the cleanest ghost shape.

Press the coated thumb firmly onto the centre of the card blank and lift straight up without rocking. The thumbprint should be a clear oval. Leave it to dry for two minutes. White ink takes a little longer than coloured inks to become fully opaque; hold it to the light to check before drawing on it.

Once dry, use the black marker to add two small dot eyes near the top of the print and a small mouth if you like. Draw a wavy hem line below the thumbprint, extending slightly wider than the print on each side, to give the ghost its floating skirt shape.

Write a name, a message or a number on the card. Add tiny stars or dots around the ghost with the orange or pink marker if you want to fill the card a little more. Finished cards look lovely tied to a treat bag with a loop of twine.
