I do "kite art"...
I reycle EVERYTHING (easy to tell as soon as one walks in my place).
I use the canopy instead of cotton on my canvas frames, I make translucid lamps, I've once hanged my kite up the walls and used it as a diary, I make collages with torn canopy, ripped lines and various bits and pieces, I'm currently sitting in front of a table that's a destroyed kiteboard, I use old chicken loops as clothe hangers, the possibilities are endless! And that doesn't include the multiple options between massive tent for the camping trip, the shower curtain, the gift wrap (very stylish! With the rubbon around like on your freshly bought kite!), the table cloth, the motorbike cover, I mean, you can basically do with kite canopy ANYTHING you could think of doing with paper or fabrik.
The rest is just imagination...
How about launching a clothing line made of kite leftovers only... The bladder range could be interesting...

PS: Any addition to my current stock would be welcome! (Think I spotted an empty corner in my garage...)
