Natural Inks
Cultus Bay Gardens on Whidbey Island, Washington
August 3rd, 2025
10 - 4 pm
$125 all supplies included
Natural inks offer an intense and unique color range that watercolors cannot achieve. Many natural materials work well as ink but not as watercolor, and we will learn to differentiate these qualities in this workshop. Starting with foraged materials, we will make dye-based inks from start to finish. We will extend the color range by manipulating pH, mixing in minerals, and combining multiple pigments. You will leave with six unique 1 oz ink bottles made together during the workshop.
Techniques covered in this workshop include identifying sources of color in nature, making dye-based inks, making lake pigment-based inks, ink binder recipes, extending the color range with iron, copper, & pH, and making UV reactive mushroom ink!
​
There is no overlap in content for the Botanical Watercolors and Natural Ink workshops. Participants will gain new information and skills by taking both workshops.
