As I mentioned, I work for a fairly conservative company so I did not like the idea of wearing them to work. What I did was to get some clear nylon line (heavy gage fishing line), cut it about 1/4 inch, soften one end with a flame, and the tamped the one end flat. More or less, this created an almost invisible stud that was very unobtrusive. Note that I said "unobtrusive", not invisible - this would not be a way to hide them from your wife. I've heard that these days you can by something like this off the shelf
