Edible images of a poker hand & chips.
Just cut around them, remove the backing & place on your cake. Just brush or dab a small amount of water onto your fondant iced cake to make them stick. For soft icings placing on fondant as below would work best.
For a more realistic look roll out some white (or coloured) fondant until it's around 3-4 mm thick, dampen evenly with a pastry brush or a handee towel, place on your cut out images & cut around.
Sheet is around A4 size.
They can be brought a few weeks in advance & will keep well if left in the bag until use.
