Besides ink for drawing, a fountain pen and colored ink for writing is also a good thing to have lying around, but contained in a bottle or pen, of course. I am out of homemade iron gall ink and my quills are a bit bedraggled, so I’ve resorted to more modern technologies for awhile.
Beds of dried, caked and cracked mud are fascinating. Footprints in them are even better, or the mysterious sliding rocks found in Death Valley. I looked at a lot of pictures of mud flats, and one thing I noticed were curves and angles as well as the way light bounces off their slightly uneven surfaces.
Here I used ink and water, specifically Private Reserve’s Copper Burst. I have never considered using fountain pen ink as a painting medium, but it’s opened up my eye to its potential.
