Start by mixing salt, wheat flour, and oil in a bowl.
Then add a little water at a time. Continue until it resembles playdough - it might require slightly more or less than 1 dl of water.
Let it rest on the kitchen counter for an hour before continuing. Use either a tea towel or a shower cap over the bowl.
After an hour, preheat the oven to 100 degrees Celsius (212 degrees Fahrenheit) conventional oven.
Now, roll out the dough relatively thinly and cut out shapes.
I chose to make them as hearts with a hole at the top so they could be used as Christmas tree decorations.
At the same time, my children's names were written on them.
Bake them in the oven for 4 hours and let them cool on a rack.
They should become slightly golden on the edges.
Note, they are obviously not edible.
