My brother wears his ring on his right hand; think he broke his left finger and can't get it on that hand anymore. You wouldn't want to go telling him that means he's divorced.

My jeweler soldered two little gold balls on the inside, palm side of one ring shank. Gave me a bigger weight range for the ring and it's hidden and doesn't get all dirty and grody like the tape or string methods do.

I've moved several rings from my left hand to my right, and one's off my right for the duration until I have enough rings in need of resizing to warrant a trip to the jewelers. In a pinch, you could wear rings on the middle finger, too--most wedding / engagement rings are pretty obvious as to what they mean.

In a pinch, you can buy a plain gold band at WalMart or Sam's for not very much at all and put your real ones away until goal.
