More experiments with lichen. I collected the lichen to dye this yarn off rocks and stone walls while I was in Co. Mayo in June. Fermented in in ammonia for several months and then used it for dying. I had high hopes for interesting colors, but no luck!! The slightly darker skein is one that I had used chrome as a mordant but there was little difference . The wool is a pleasant tan color after several months wait. Maybe I collected the wrong lichen
