This is a summary of my first experiment with lichen dyes. I scraped the lichen (a flat, blue-green lichen that is common on our maple trees here) off the wood with a knife, then let it soak in a 50:50 ammonia:water bath for 6 weeks. I used a few tablespoons of the ammonia/lichen concentrate in ~2 cups of water to make a dye bath and inserted a mini-skein of border leicester wool yarn.
|Dye on left, concentrate on right. Dyed mini-skein on ball of un-dyed wool.|
The result? A very pale, unsatisfying yellow. The dyed mini-skein is on top of an un-dyed ball of the border leicester yarn in the picture. The mini-skein did not take up much color.
