from Joan Justis
I discovered a creative media for drawing. It is filled with surprises and a natural beauty. Every age will enjoy it. You need food coloring or colored inks, an eye dropper, a drawing pen with a round tip nib, and a pad of calligraphy paper (it does not absorb the water). If you used colored inks a fountain works. Now watch this!
As you can see, that was done with colored inks and a fountain pen.
You can let a color dry before you apply water for the next color, or you can purposely let them run together creating special effects. You can sprinkle salt on the wet drawing to add texture. Try a sunset or a fish bowl or a flowering branch. Try design borders and patterns. Make your own stationery and greeting cards. Have fun!
