The Diné trace their knowledge of weaving and design to two holy people: Spider Man, who created the vertical loom, and Spider Woman, who taught them how to weave. These blankets typically were worn around both shoulders or wrapped around the torso with one end draped over one shoulder. Designs started with simple banded horizontal stripes and became increasingly complex over time. The predominantly geometric patterns of wearing blankets manifest the essential Diné concept of hózhó: the harmony and order that come through a balance of apparent opposites, such as day and night, which permeates the world.
