Samples of wool which I dyed with various natural dyes last summer. They are Brazilwood, Madder, White Onion skins, Red Onion skins, Turmeric,Weld, Indigo and Ornamental Maize and some which are a mixture of two of these. They were all mordanted with Alum.
Wool and Dyes Oaxaca The bowls in the back contain a variety of substances which can be used to dye wool yarn. All of the skeins of yarn in the foreground were dyed using these natural substances. Pretty amazing. Seen at the home and workshop of Sr. Bulmaro Perez who lives in Teotitlan del Valle Oaxaca Mexico.
Natural dye technique from Etsy labs using tumeric, golden onion skins, or red cabbage. I notice there are no mordants unless salt is considered a mordant. (Alum salt is a mordant, but I don't if know plain salt is.)
