Aaaa, like a men's tie, that makes sense!
I played around with my silks, I think I made it (with a 90, so it looks differently).
Then I came up with a way to make it easier: Just held the silk up an one corner, tied a simple knot in that corner, put it around my neck and pulled the longer side through it (kind of like a very asymmetric variation of lanit's favourite knot).

Next I kept playing and wrapped the long tail around my neck and pulled the corner through the first loop and got some kind of cowl. Might be nice when temperatures drop.

I had lots of fun using a day off for playing with my silks, thanks for teaching us Prof. Cavalla
Look at them! How beautiful are they! Love how you wear them and particularly that la mer au ciel!
