I found probably the most fantastic and beautiful lavender painting today, that has ever been painted on a biscuit. Its preparation is super simple, of course only to someone who is so experienced in the handling of frosting.
Nothing else is needed for the biscuit then a biscuit base and 3 colours of frosting: white, purple, green. The rest is only a matter of manual skill.
If someone has taken an inclination to prepare such a work of art should look at the pictures in more detail on the Arty McGoo blog, which describes biscuit painting.
