I have a few scarf rings. One horn ring that I bought to use for shawls. It also works with silks. I finally found two of my grail rings -- a square one (I found on the QM2 Hermes Boutique in December,) and a long wooden/mother of pearl loop. It's about 3 inches or so. My SA taught me how to use it on a regular 90 as well as a GM. It was really a find at an H sale. The best thing was DH was able to remove the "S" mark from it without marring the wood, so it is reversible.
