You have very good advice in the answers of your post. I just only add that you can use fashion as help to attract attention where you want and get off it from your hands. For example use only narrow rings and not as many, maybe you can use pretty bracelets as they make the sensation of thinner arm and hands. The same with watch. And be careful with the nail color you use when do manicure, maybe is not a good idea use garish or strong colors.
I hope this few experiences help you.
