What were the Sioux tribe dream catchers made from?

Sioux tribe dream catchers were traditionally made from a circular frame of willow or other flexible branches, which were often wrapped with sinew or thread. The center was woven with a net-like pattern, sometimes incorporating feathers, beads, or other natural materials. These elements were believed to filter out bad dreams while allowing good dreams to pass through and reach the sleeper. Dream catchers held significant cultural and spiritual meaning for the Sioux and other Native American tribes.
