I found the answer ... Compare the GM Cut & Legendes de L arbre 90cm from 2016AW - both have that bicolor thing going on , so a few LdA photos are helpful,with something akin to a cowboy knot - photos from h.com

OK, i do note how meticulously the folds are done - I could never be that careful but the bicolor diagonal look is striking, I love how the ends of the blue scarf are different colors. But, of course a bandana is smaller , ends are shorter so, you could not get that effect.
And Cheval Surpise Coloriage is also a good example , here in the small 45cm

Here the scarf is turned a bit to the side and you see the different color ends on the gavroche, esp the blue - cool
