How to make a big festival kite - Tangens Delta (Part 1)

I have been told that it is "of high importance" to show how I made my Tangens Delta kites, so I've made an effort to film how I did the last one.
Please note, that I make these kites as a hobby and for my own amusement. The copyright for commercial production lies to my knowledge with the kite designer, Heinrich Vogelmann.
You can find further details on Kite Plan Base website. A good website to find other construction plans for kites.
Part 1 shows the dimensions of the kite, materials and overview of steps I use for making the kite, and how the panels are sewn together using a felled seam.

Very well done explanation, Monika. I have the commercial version of this kite, and my sewing skills are probably not up to making my own version, but I'm sure a lot of people could find your video very helpful.

Thank you, Jim. It was hard to work and film at the same time, so the quality of the filming isn't great at times. However, I did my best...
