Sorry to read previous review as I think these plaster of paris mould sets are great (unlike shaker maker which was a messy waste of time). Add a little water to the bag of plaster of paris, mix, pour into moulds (you can add a magnet when its just starting to thicken), leave to set for a few hours, carefully pop out of the mould,(the fairies should be hard and shiny) and then use the paints to decorate.
There are two bags of plaster included so you can make another batch of fairies another time.
My five and 10 year old love them and enjoy giving them to gran or whoever afterwards.
