In a web search I ran into a bibliography of Bread and Puppet sources that included the following excellent making resource:
Peattie, Sara and the Puppeteer’s Cooperative. 68 Ways to Make Really Big Puppets.Glover, VT: Bread and Puppet Press; St. Johnsbury, VT: Troll Press, 1997. 10 pp., ill.Instructions for simple puppets, animals, dragons, giant puppets, hoop and cloth puppets.
This booklet is available online at http://www.gis.net/~puppetco/
I've added this as a link to the side of the webpage. Well worth looking at as preparation
