I prefer dangles attached on each individual link - otherwise I think they bunch up in the middle. My parents bought me a charm bracelet for Christmas that I'm going to put all my dangles on. Part of my issue is that I have two badges - a "rescued" pearl one (thanks
GPhiBLtColonel) that is all gold and older than my mom is, and a two-tone standard badge that's my initiation badge. I'd feel funny putting my dangles on the fancy badge, but I wear that the most, and I'm considering having my badge made into a ring. I figured on a charm bracelet I wouldn't feel torn and could wear it whenever I wore my badge.
