@bbkite , I thought it had to do with the white color of the kite that we can see the yellow glue but you have a point core kites are white also and I havent seen this effect
@jonysan It happened to three of the pannels already. I guess I can stich it back myself to fix the loose ends but it still leaves the problem of the glue. Honestly I'm not sure that the glue plays no role in the general endurance of the kite, I mean only the fact that sand can get in the joints of the pannels can't be good . On top of that I guess it would affect the possible resell price
