I think I'm going to start looking at scarf rings -- not Hermes though, I can't realistically afford them, and want to save the $$ for the scarves themselves.
I often use rings that are not Hermes. I have gone to a very upscale fabric store here and looked at the plastic belt loops. There are a bunch that are perfect scarf rings and they come in all kinds of colors and sizes. Just make sure that you carefully run your finger along the edges to be certain there are no little "blips" that could snag a scarf. I also use Murano glass rings - there are a ton of them on eBay that I think are probably not real Murano glass, but what I like are the colors. The glass that I don't think comes from Murano is still pretty and is orders of magnitude less expensive. So most of mine are those, but you also need to do the finger test to make sure there is nothing that would snag a scarf. I have read over and over that many metals can leave a ring on scarves, so I tend to stick with my H rings, my glass and my plastic!!
