I just finished dyeing sampling skeins for my indigo demos in Turkmenistan. I dyed with Cochineal (reds) and Fustic (yellows). The yarns are (from left) wool, silk, an organic cotton/bamboo blend and a cotton/rayon blend. For the demo they will be over-dyed with indigo for a beautiful range of purples and greens! The undyed skeins will give a range of indigo blues as each substrate will take the indigo differently.
If you would like to try this, these same dyes are featured on The Yarn Tree’s website
