Never tried cuff links,think I'm guilty of being sexist with my jewelry :-/ .... I did make a men's ring a couple of times.Thats a cool idea though :-)
I've been meaning to try out cufflinks, but haven't gotten around to it yet. I'll have to make some for my husband to try out. I have made tie bars for him and his brother, I'll probably put some in my store soon.
Simple tie bars are pretty easy, and there's lots is scope for different variations. My husband likes his a lot, they work pretty well as long as you make them grip tight enough but make sure they won't snag the fibers.
