Okay, this was quite a project. The recipe was simple enough:
2 cups plain flour
1 cup water
3 tsp lemon juice
Once mixed, the dough is rough, but kneading for a while makes it more pliable. It rolls out well, and cookie cutters work really well on this dough.
Keep some excess flour on hand to dip cookie cutters into, and to dust rolling pin, bench, etc.
I put them on some baking paper, and will put them in a warm sunny spot to air dry for 2 days (if you want to speed it up, place in oven for a couple of hours @ 120°c).
Remember, before drying (or baking), to put holes in the tops for your ribbon to thread through if you want to hang them on the tree when finished.
Once dry I'll paint them up in Christmas designs.
Oh P.S, leftover dough can be wrapped in cling wrap and put in fridge.
