Although some Hermes scarf rings are helpful when they are double sided (with 2 holes) like the Mors scarf ring or Chaine d’Anchre, when you just need 1 opening, a ring is perfect. And why not add some sparkle? A bigger ring will work better with a size 90cm scarf and a smaller ring for a 70cm or 45cm, like I have here. For reference this ring is a size 4.5.
