I got *really* into leather fringe a few years ago. It started slowly and bloomed into a full-blown obsession -- and now I collect vintage leather jackets, and spend way too much time on ebay hunting down vintage and one of a kind pieces. And I have to say: I really do get stuck in car doors pretty frequently. And I accidentally get fringe in my coffee, or lightly whip people when I get too excited going in for a hug. Worth it :).
Leather fringe is an old cowboy standby, but it actually originally served a functional purpose on buckskin jackets and chaps, helping to wick the rain off and allowing the garments to dry faster.
