Q: We have a potential application for an inflatable form shaped like an 18-inch-thick pancake about 12 or 13 feet in diameter. However, we can't find a source for inflatable forms. Can you help?

A.: We know of one source: Monolithic Constructors Inc., P.O. Box 479, Italy, TX 76651 (972-483-7423; fax: 972.483.6662; e-mail: mail@monolithicdome.com). Do readers know of any other sources?
