It sounds like you did a hacking knot without knowing it! Btw, I love other rings for scarf rings, and thought yours looked great. I have three beautiful sterling silver rings I bought from different artists in Santa Fe, and they all look lovely as a scarf ring. I just make sure I polish them before using to make sure they haven't tarnished.
I think I will just find a high quality (smooth inside) ring. There's no need for an H ring huh? Even though I love H, that's almost a price of another maxi twilly! This particular ring is a heavy David Yurman ring (borrowed from DH), If it falls off, I'm out $1200 😫
