Line 2 baking sheets with non-stick baking parchment.
Put the sugar into a bowl, add 1–2 tablespoons cold water and stir thoroughly until the sugar feels like damp sand, like when you're making sandcastles.
Divide the sugar mixture up depending on how many colours you'd like to use.
Using a toothpick, add a minute amount of colour to each portion of the mix. Combine well.
Place one colour onto one of the baking sheets and press firmly or use a rolling pin gently to flatten to a thickness of about 1cm.
Using a small shaped cookie cutter, stamp out shapes. Gently push each sugar shape out of the cutter and onto the second baking sheet. Repeat until you have used up all the different mixtures up.
Leave to dry overnight. Do not place/store in the fridge.
Pack in something pretty and label if giving as gifts.
