Natural Wool Dyeing

Yesterday two friends and I came to the village of Teotitlán del Valle to attend a 3 day workshop on dyeing wool yarn with the locally used methods. This village is well-known for its rug weavers, and almost every family in involved in weaving beautiful wool rugs that are hand dyed with mostly natural dyes.
(My friend's husband is doing a class in weaving with a small backstrap loom, and the two of us are dyeing)
Today we washed the already spun wool and prepared it with the mordant (alum fixative that also helps rid the wool of lanolin and make the color brighter), and we prepared the first dye with a plant called pericón, which they gather in the mountains after the rainy season. We boiled the wool in this dye (yellow) and it is now resting in the dye until tomorrow.

The people here are Zapotec, and most speak that language as well as some Spanish, so we had a translator who also spoke English.
