For the marbled version, proceed as described above, but add a little more colour in orange and white to the mixture in the casting moulds. Go through the colours with a bamboo skewer to create a pattern. When you are happy, blow-dry over it again and leave it to dry.
Check after 24 hours to see if the bowl is completely dry. If this is the case, remove it from the mould. If necessary, you can leave it to air dry further.
Cut strips 27 cm long and 2.5 cm wide from the kraft paper for the banderole. Fold them to fit the bowl and write the message on them. Stick the ends of the banderole together on the back using double-sided adhesive tape.
