This image shows  an extended Ecuadorian native family as they show their handiwork with wool.
The description states:
A COLORADO INDIANS’ FAMILY
with a primitive loom where they weave their cloth. – ECUADOR
–The term Colorado is no longer used, and the most likely identifier for this family is Kichwa, which identifies a linguistic group more than an ethnic one, but this group accounts for about 94% of all native Ecuadorian people.
