Hi I am having difficulty in sizing spinner rings. I made one up which was 12mm wide in silver and I reckoned it needed to be at .least one size up from the persons normal size if I had been sizing for a thinner ring. The base of the ring fitted the person but once I put the spinners on and bevelled out the ends the ring was too big. My question is does the ring stretch in size when you bevel out the ends to keep the spinner rings on.
