Step 1: In a large mixing bowl, combine the all-purpose flour and fine grain salt thoroughly.
Step 2: Gradually add the warm water, about 1/4 cup at a time, mixing with a spoon until a shaggy dough forms. You may not need all the water.
Step 3: Turn the dough out onto a lightly floured surface and knead for 5-10 minutes until it is smooth and elastic, similar to play-dough.
Step 4: Roll the dough out to your desired thickness (1/4 to 1/2 inch is ideal for most crafts) using a rolling pin. Use a little extra flour if it sticks.
Step 5: Use cookie cutters, a knife, or your hands to shape the dough into ornaments, handprints, or other crafts. For hanging ornaments, use a straw to make a hole before drying.
Step 6: Carefully transfer your salt dough creations to a baking sheet lined with parchment paper.
Step 7: Bake in a preheated oven at 200°F (95°C) for 2-4 hours, or until completely dry and hard. Thicker pieces may take longer. Alternatively, allow them to air dry for 2-3 days, flipping occasionally.
Step 8: Once completely dry and cool, your salt dough crafts are ready to be painted, sealed, or decorated as desired. Ensure they are fully dry to prevent mold.
