Hi Emine,
The butterflies are fondant with some tylo added for strength. I used 2 different sized cutters and then dried them over folded card to get the open wing shape. When dried i dusted the centres with pink dust and then painted the tips with edible lustre paint. I used royal icing to make the body and to stick them to the cake!
