This is part of a rak that I'm involved in. The person who is doing it works for a coffee/tea company who also makes coffee makers. The company was kind enough to donate a coffee maker for the prize. My husband and son love coffee and I love tea so this was fun to do. The transparancy has dates that are important to the history of tea on it such as the Boston Tea Party and in the beginning when tea was discoved by the Chinese Emporer in 2737 B.C. when it blew into his cup of hot water.
