Flatten each fairy cake case and cut into quarters. Decide which mix of patterns you’d like for each tree ornament – you’ll need four quarters per decoration.

Put some glue on the pointed top of a quarter (this one will be at the bottom of the ornament), with the curved edge facing towards you. Put another quarter on top, facing the same way and making sure a little of the first case is still on show before pressing down into the glue. Repeat twice more. There should be four quarters glued on top of one another to make a tree shape.

Cut a 15cm strand of string or ribbon. Punch a hole in the top of the ornament, then thread the string through and tie the ends together. Repeat the process with the remaining fairy cake cases.
