Notes
Colouring options ~ Food colouring can be used, gel colours give the best colours, liquid watercolours also work. Natural colourings can be use, they just won't be so vibrant. For orange/yellow add turmeric; for red, boil beetroot for at least 10 minutes, strain and use the water; for green, boil spinach for 10 mins, strain and use the water. Kool aid can also be used, but it may alter the scent.
Scents ~ Just one or two drops of essential oils can be used, just check the safety for the oils before using. Extracts such as vanilla and peppermint can be used but start with a small amount as you can always add more.
Extras ~ Glitter is great for that sparkling effect. Sequins can also be added.
