Add the olive oil and essential oil, and then the boiling water.
Begin to mix the ingredients together, and then add your natural food colouring.
Stir thoroughly until the playdough ingredients are completely mixed.
Once the playdough is mixed well enough not to be too sticky, you can dump it out onto the kitchen step and knead it until it’s smooth and ready to use.
Store in an air-tight container for up to 6 months.
