You would need the ingredients here below:
Green, yellow and red food colouring,
Some Christmassy shaped biscuits cutters
A bit of water.
A few small bowls and a teaspoon.
Here is how you make your decorations:
Take 12 tablespoons of granulated sugar and add 2 teaspoons of food colouring.
Make three bowls like this, each with a different colour- one gree, one yellow, one red.Or you can go for just yellow and green , which is what I did.
Mix well. The mixture has to have an even colour ( green, or yellow, or red).For the mixture think wet sand like when you build a sandcastle. So: not too dry, and not too wet.Add, if too dry , a tiny bit of water.
Roll out some baking paper.
Take a Christmassy themed biscuit cutter ( star, tree, bell, or otherwise) which has a high-ish edge.
Using the baking paper as your worktop on which you will make your decorations, fill the biscuit shape with the sugar"sand"- and compact well with your finger or the bottom of a teaspoon.Loosen the shape by using the handle of the teaspoon like a small knife and go all along the edges ,so the shape of the star or tree or whatever shape you have chosen , pops out onto the baking paper.
Let the shapes dry.This may take about 15 to 20 minutes.The sugar will become pretty hard.
Wrap the shapes in cellophane and tie with a ribbon.They are now ready to be hung from your tree.
You can improvise a small tree by taking some branches and spraying and / or painting them white and putting themin a wicker basket with some evergreen cover at the foot of the "tree".
Hang your decorations from the branches and you are done!
