The Arapaho have always shared everything with each other. When buffalo hunts occurred, it was the custom for those who were successful to give to those who were not. Everyone supported their immediate and extended family, and others as well. This was known as a "gift economy," and everyone trusted that if they gave, they would receive in return later. When anyone helped out, as a doctor, or by saying a prayer, or for whatever reasons, gifts were given in return.
There were also ceremonial gifts, including horses, blankets, beaded and quilled items, and other objects. These special gifts were given to honor people, often before the entire tribe. Today, Arapahos continue to practice elements of the gift economy. If you win big at gambling, you're expected to give away to family. If you have a job, you support others on your salary. If you have a house, you let others live there. At the Sun Dance, there are a whole series of ceremonial dinners exchanged between different members of the tribe.
One symbol of generosity, as well as a special gift in and of itself, is the Star Quilt. Click on the image of the quilt below to read about them, in a page contributed by Lisa Redman Hill of Wind River Reservation:
