In a large bowl, mix together the flour, salt, and warm water.
After ingredients are combined, I like to mix the rest by hand on a countertop.
Next, knead together the salt dough until nice and smooth.
Roll out with a rolling pin until you reach your desired consistency. I like to aim for about 1/8-1/4" thickness.
Use cookie cutters to create shapes. And use a small screwdriver or kitchen skewer for creating a hole to hang the ornaments after they bake.
Line baking sheets with parchment paper and bake in the preheated 300 degree oven for about 1 hour. Large shapes and thicker ornaments may need a little more time added to them. I start checking my ornaments around 40 minutes. They will be done when they become hard.
Allow to cool and hang with your preferred twine or ribbon.
You can paint them or use something to seal them if you'd like. But that is totally optional and we never do that.
