The 30 page publication Flights of Fancy: An Introduction to Iroquois Beadwork contains a description of the various types of Iroquois beadwork. Iroquois beadwork represents two major traditions:

• Niagara, made around Niagara Falls by beadworkers from all the Six Nations, but primarily the Tuscarora.
• Mohawk, made near Montreal by Mohawk beadworkers.

Although the Tuscarora are more widely recognized for their beadwork, Mohawk beadwork, in fact, outnumbers Niagara beadwork 10:1. Because the book is no longer in print the following excerpts are available here.
