Fill the loops with Helium. Of course you would have to have 2 layers of material to make a pocket.
The Helium would last a few weeks.
It would also give the kite a more playful look.
Just a thought.
......I suppose I should have expected that!!
I was once asked how I could be flying a kite ( the Shadow) when there wasn't any wind.....I told him it was made of anti -gravity fabric!...he seemed happy enough with that!
I've a feeling it may be my lack of SLK experience that may be a lot of the problem.
