@201217 When it gets to the part of the pattern where they split away from each other, continue until you've got about an inch of two divided parts. Then cross them over, and continue the beginning if the pattern, only now, the colours are switched
@Fl27vy depending on how many times you cross, it will look differently You also need to make sure that the two halves are still crossed properly when you start connecting them again
@halokiwi, Yes, sorry, the French - English translation must not be simple. I said that I succeeded with the model because it is simple but my two colors don't mix like in the photos, I don't know why.
