Online Workshop: Chromatic Transformations: Natura Online Workshop: Chromatic Transformations: Natural Dye Chemistry and pH-Responsive Color Shifting on Cotton & Silk – August 9th, 2025 with @caramariepiazza


Starts at 12pm PST/3PM EDT 
Ends at 2:30pm pst/5:30pm EDT

Online Via Zoom : You will receive a PDF with the zoom link after purchase. Once the date nears closer to August, Cara will send the class curriculum and PDF. 

This workshop will be recorded and available for online viewing until March 15, 2026.

Originally Cara’s workshop on creating cosmic night sky patterns,  Cara has now modified this workshop to include an entire range of tannin bases, along with other dyes that are susceptible to being modified with simple kitchen chemistry. A great addition to Twilight Tannins, you will build and create swatches on both Cotton & Silk in this workshop. Cara will guide you through methodical approaches to dyeing and how simple changes in pH can create stunning, shifting colors on fabric.

What This Workshop Is About
Natural dyes have a unique magic, terroir and alchemical properties. Many of them change color depending on their chemical environment. In this class, you’ll learn how to work with these dyes in a thoughtful, hands-on way, experimenting with acids and alkalis to shift colors and create beautiful, otherworldly surface designs inspired by our galaxy.
