Brilliant idea about the jewelry. I do that with mine on the rare occasions I go on a trip where I’m going to make an effort with jewelry. More commonly, I just pick one set of neutral earrings and wear them all the time.
I usually just take one set of jewelry with me when I travel, to go with a nice outfit for church or dinner or whatever might come up needing me to look nice.
But I just can’t face a scarmabled mess in the jewelry case. It would take too long to sort it out. Who knows? Maybe this way I can identify the sets I don’t wear very often and bag them for donation.
