M.D.
My rings spin and are loose when it's cold. When it's hot, they are tight and I want them bigger. so I guess where they are is the happy medium.
My ring finger is also larger than my left ring finger...and I am right handed. Thanks for that tip, Jo!
My wedding bands never come off (unless I'm making meatloaf or digging in the dirt) so my finger is indented where they sit. I wear three rings on that finger so it's a larger space that is indented compared to the two I used to wear.
