Would anyone know how to create a convincing milk moustache that lasts and doesn't crack. The agency for the milk campaign has approached me to find a way to replicate the moustache featured in their posters for live events. They want something edible but everything I try either dissolves on the lip or cracks when I smile. I think condensed milk is a good base product but need help in finding something to mix in that will make it brilliant white but at the same time is edible. All suggestions welcome!
