SCENTED ROCKS 
Place rocks in a bowl or dish to scent a room. A nice alternative to potpourri! 
1/2 cup plain flour 1/2 cup salt 1/4 teaspoon essential oil (your favorite scent) 2/3 cups boiling water Food coloring, if desired 
In bowl, mix dry ingredients well. Add essential oil, and boiling water to dry ingred. (Scent will be strong,  but will fade slightly when dry.)  
For colored stones, blend in food coloring, one drop at a time until desired  shade is reached. 
Blend ingredients, and form balls.  Allow stones to dry.
