Fog-free bicycling scarf

I like to wear a light scarf over my nose and mouth on cool morning commutes. Unfortunately, my exhaust breath fogs my glasses, as it sneaks up the gaps on both sides of my nose. It's bad when I ride slow with my head upright, and worse when I stop at a traffic light.

To fix this problem, I sewed a piece of insulated copper wire inside the top edge of my scarf, with the wire bent to fit the contour of my nose and cheeks. It closes the air gaps, and eliminates almost all the fogging. (Click on the thumbnail photo to enlarge the result.)

Here is a complete tutorial in photos. Feel free to copy and improve upon the idea.
