I can't wear mine when my hands break out. When my fingers start itching and cracking, I can't put anything on them except lotion/topical medicine. So, I wear my rings on a necklace. Unfortunately, the only necklace I could get when I needed one for the rings, was a cheap one. Because of this, I only wear them when I leave the house.
Hubby takes his off every night and puts it on as soon as he gets up in the morning. The only time he doesn't is when he is asked to work on dad's van or any other friend or family's vehicle.
The only other time neither of us wore our rings was like Hope's husband... but, like him, we put the rings back on when we chose to recommit to each other.
