I've been thinking to start practicing basic magic slight of hand stuff with a ring, looking online there's of course all sorts of gimmick rings , then regular titanium rings , rings with magnets , lol smart rings ? .. anywho is there rings better than others for "ring magic " ? Should the ring be sized for let's say my thumb over my ring finger ? Should it be metal ? Can it be those new silicon? Any little help is much appreciated. Thank you .
