When I first started dyeing, I read that I should dye to 1-2 Depths of Shade (DOS) darker than the final color I wanted. I had no idea what that meant, practically: "depth of shade". So, I hit the books & google... and I found references in painting and in photography and a scale such as the one, below:
"OK", said I, "how do I apply that to natural dyes and dyeing for craft?"
Below is a small video where I show what that looks like in the Dye studio. If you find it helpful - YAY. This and many other topics are covered in my online Workshop: Become a Home Natural Dyer. If you've always wanted to up-cycle your clothes, explore natural color, play with natural dyes, or just love to learn new things about the natural world, this course if for you!
