Step 1: In a large mixing bowl, combine the 2 cups of all-purpose flour and 1 cup of fine table salt. Whisk them together thoroughly to ensure the salt is evenly distributed.
Step 2: Gradually add the warm water to the flour and salt mixture, starting with 3/4 cup. Mix with a spoon until a shaggy dough begins to form.
Step 3: Turn the dough out onto a lightly floured surface. Knead the dough for about 5-10 minutes, adding a tiny bit more water if it's too crumbly, or a little more flour if it's too sticky. You're aiming for a smooth, pliable consistency, similar to Play-Doh.
Step 4: Roll out the salt dough to your desired thickness, typically 1/4 to 1/2 inch, using a rolling pin. Thicker pieces will take longer to bake.
Step 5: Use cookie cutters, knives, or your hands to cut out or shape your desired creations. For ornaments or hanging decorations, don't forget to poke a hole at the top with a straw or skewer before baking.
Step 6: Carefully transfer your salt dough creations to a baking sheet lined with parchment paper. Preheat your oven to its lowest setting, usually 200-250°F (90-120°C).
Step 7: Bake the salt dough creations for 2-3 hours, or even longer for very thick pieces. The exact baking time will depend on the thickness of your items and your oven. They should be completely dry and hard to the touch when done. If they feel soft, continue baking.
Step 8: Once baked, turn off the oven and leave the salt dough items inside to cool gradually, which helps prevent cracking.
Step 9: After cooling completely, your salt dough crafts are ready for decorating! Paint with acrylics, add glitter, or seal with Mod Podge or clear varnish for durability and a protective finish.
