Here is a good way to make your own watercolor paint. This will make a good substitute to commercially available watercolor paint.
What you need:
1 tablespoon (tbsp) white or cider vinegar
2 tbsp baking powder
1 tbsp corn flour
½ tbsp glycerin
2 drops food coloring
1 teaspoon water
What you will do:
- Mix the vinegar and baking powder in a small bowl.
- Add the corn flour and glycerin when the baking powder stops foaming.
- Stir in the food coloring and add water if the solution seems to stiff.
- Store in a tightly covered jam jar or plastic container.
