Hi! Sorry for the delay in answering the question. We used the designs from Glenn Davison's book (available for $9.99). He is a huge supporter! We built the Korean Fighter Kite and Rokkaku kites on pp. 43 and 44. He also has many more kite websites, all listed at http://www.kitingusa.com/ including one on Kites in the Classroom that I'm definitely going to check out. Have fun!
