Directions
- 1Cook baking soda mix until thick dough.
- 2In a saucepan, combine baking soda, cornstarch, and water.
- 3Stir well until the mixture is smooth.
- 4Place the pan over medium heat and keep stirring until the mixture thickens into a soft dough-like paste.
- 5Remove from heat and let it cool until safe to touch.
- 6Separate the dough into 3–4 small portions.
- 7Add a few drops of food coloring to each portion and gently knead the color in.
- 8Take small pieces from the colored doughs and lightly twist them together.
- 9Roll the mixture between your hands to form a small oval stone.
- 10Press your thumb gently into the center of the oval to create a small thumb groove.
- 11Smooth the edges with your fingers.
- 12Place the stones on parchment paper and let them dry for 24–48 hours until fully hardened.
- 13Brush a thin layer of clear glue or Mod Podge over the stones for a glossy look.

Tips
- Do not mix food coloring fully - leave streaks so the colors create a marbled swirl effect.
- Flip stones halfway through drying so both sides dry evenly.
- Brushing a thin layer of clear glue or Mod Podge makes stones smoother and shinier.
