I’m obsessed with thread shading. I want images to be as 3-d as possible. To do that I shade with as many colors as I can. With regular #40 embroidery thread, I can use almost an infinite number of colors to shade an image. Particularly for a larger image. It’s a pretty large paint box. And you can use them all.
With heavy weight bobbin threads, there’s just not that much space in an image to shade. So this is my answer. Instead of adding more and more colors, I dye the thread so that it’s got a range of color within each thread.
Most commercially dyed thread comes in one of two styles. Either they mix a dark color with a number of lighter shades ending in white. Or they do the rainbow either in pastels or brights. The rainbow color ones work for stippling. They don’t shade well at all. The ones with dark to white leave a white area I really don’t like.
Most images can be zoned in dark, medium and light areas. They also can be zoned into different colors, like the spots and the frog’s body.
Dyeing threads to shade images can be set up the same way. You can dye a shader, a shocker and a smoother. The shader thread is the color of your image darker than you want the whole image to be. Add in a dark shading color like dark brown, purple, green or blue, or it’s complement, plus 4-6 dark shades of the whole color. The shocker is a medium range of 5-6 colors with a shocking color mixed into it. Usually a bright complementer color works best as a shocker. The smoother is a color that is a bright highlighter shade that fills in the image and finishes in the shaded image.
The range of colors gives you at least a 15-18 color range in a small bobbin work image. Other colors can be added. There are no rules, but here are some color ranges that work well.
Shader: Dark orange, yellows and reds, and browns
Shocker: Yellows and two purples
Smoother: Yellows and oranges
Shader: Dark purples, blues and greys
Shocker: Medium greys and teals
Smoother: Medium to light purples
Shader: Teals, and oranges
Shocker: Yellows and teals
Smoother: Yellows, and oranges
You get the idea. Dye the thread to do your shading for you. As you fill in the stitching with rhythmic motions, the shading progresses across the image. All you have to do for thread like that is dye for it.
