The making of a new collaboration, 1993 to 2018. In the early years of my attending the Fanoe, Denmark, International Kitefliers Meeting, I was greatly impressed by the tetrahedral kites of Til Krapp and Peter Malinski. Malinski, an inspiring artist had become a close friend and, along with Denmark’s own Jorgen Moller Hansen, had convinced to come to Fanoe in the first place. Til Krapp had a background in medical and dental equipment and he was the one who developed the plastic fittings used in their tetras. So, with something to trade (sewing skills), I proposed a trade with the two of them; I’d make 50 sails for each of them if they would make me enough connectors for a 50-cell tetra for myself. The following year was the payoff, three, fifty-sail tetras, all made with sails made by me, and tetra fittings by Til and Peter. 25 years later, the tetra-bug bit me again and I felt that I might go another direction of the critical fittings that make this project possible. Enter Lindsey Johnson, longtime kite maker and innovator, who was demonstrating a great aptitude for 3-d modeling and innovative kite hardware. Using Til’s original fittings as a guide, Lindsey developed a 3-d-printed fitting that could serve the same purpose. As I had done in the first collaboration, I had Lindsey make fittings appropriate for Easton arrow shafts (1/2 a shaft for each stick) for this tetra design that features internal, 4-stick cells. I would add, that it was at about this time, as fittings were being made, that I decided upon the sail design that would make this a once-in-a-lifetime tetra; bird-shaped sails that would make a flock of birds instead of a simple, geometric, tetrahedron. (By the way, my flock of bluebirds is a “clutch”, although “hermitage” can also be used) So, almost a full year later, my almost-50-sail clutch of bluebirds is finished. Thank you to Lindsey Johnson, I know I’ll be seeing his interpretation, soon.
