Shrinkage

If you see the picture below my ring is hanging out in an unsafe place on my finger. It is not secure whatsoever. So here's my question: what products have you seen to make it more snug.

You might ask "why don't I get it resized" well here's the thing in the cold weather my hands shrink beyond belief, so I need a "fix" for now.

Any thoughts?
On Christmas Day I was in Mass and while reaching for the Bible my ring flew off and landed two rows in front of me. Thank God (pun intended) I was at Church and not on the street. Of course while everyone else is praying i'm crawling on the floor. Now do you see why I need the help!

Next on my list: mani.
