The women in Guatemala often use raw cotton when weaving textiles. They must first prepare the cotton by picking out the seeds, cleaning it, and then beating it with forked sticks. Then they can spin it into yarn and dye the threads with natural dyes: indigo to produce blue colors, cochineal for red, etc.
This is Lidia Lopez, a native Mayan woman from Guatemala, showing some of the textiles she has woven on a backstrap loom.
