The customer has given me the picture of this colorful millipede to be made on the cake. She said that's her little princess's favourite toy. Hope she is still having it now.
Just a little TIP. If you are thinking of keeping the decoration ontop of your cakes and cupcakes, just make sure you let it dry hard under the air cond or cool & dry place for at least a week. You may spray a layer of clear vanishing to keep the bright colors for long time. :-)
