Shearer is the skill associated with the shearing labor. Shearers shear the wool from creatures in a farmer's workshop. There are only three animals that can be sheared in-game: sheep, llamas, and alpacas (trolls have the necessary tokens to be sheared, but dwarves can only shear tame animals and trolls cannot be tamed). Shearable animals have [YARN] token under
[SELECT_MATERIAL:HAIR] section of their RAWs. Wool can be spun into yarn, which in turn can be used to make cloth at a loom.
Shearer is the only skill that doesn't appear to train any attributes. This may be an oversight.
