Step 1: In a large mixing bowl, combine the 2 cups of all-purpose flour and 1 cup of fine salt. Whisk them together thoroughly to ensure an even mixture.
Step 2: Gradually pour in the 1 cup of warm water, mixing with a spoon or your hands until a shaggy dough begins to form. Add a tiny bit more water if needed, one teaspoon at a time, until the dough comes together.
Step 3: Turn the dough out onto a lightly floured surface. Knead the dough for 5-10 minutes until it is smooth, elastic, and no longer sticky. Add a sprinkle of flour if it’s too sticky, or a drop of water if too dry.
Step 4: Using a rolling pin, roll the salt dough to your desired thickness, typically 1/4 to 1/2 inch for most crafts like ornaments or handprints. Ensure the thickness is uniform for even drying.
Step 5: Use cookie cutters, a knife, or your hands to cut out your desired shapes. For ornaments or tags, use a drinking straw to make a hole at the top before drying. Carefully transfer your shapes to a baking sheet lined with parchment paper.
Step 6: Dry the salt dough creations. For oven drying, preheat your oven to its lowest setting (200-250°F / 95-120°C). Bake for 2-3 hours, or until the pieces are completely hard. Thicker pieces will require more time. Allow to cool completely on a wire rack. Alternatively, air dry for 2-5 days, flipping periodically.
Step 7: Once completely dry and cooled, decorate your salt dough crafts with acrylic paints, markers, or glitter. After the decorations are dry, apply a clear sealant (like Mod Podge or a clear varnish) to protect them from moisture and provide a durable finish.
