There is a general misconception that the Wayuu Bags are made of cotton thread but they are really made out of acrylic thread which provides a colorful variety of colors. In the past, Wayuu women used to spool their own thread from natural fiber and used plants to dye it producing a narrow array of earthy tones between brown and red colors. They do not do it anymore since they can save time and effort by buying prepared thread. This also allows them to create colorful bags with unique combinations and designs. However, some of these artisans may tell you they are made of cotton since they just want to mean a fabric.
