Lakeland Silicone Caterpillar Mould Set to Decorate Caterpillar Cakes 5 "Great fun." Rosemary 19 November 2018 Tried this today. Melted some white chocolate and it worked. One issue is that the moulds are not level so everything sets on a slight slant unless you pad it straight. About to go and keep the kids entertained with mini chocolate catapillar assembling Another couple of small head moulds would time saving.
