On the horn

My friend Colin lost one of the horns he wears on his bike helmet.

He asked if I would be willing to make him another one. I love a good
craft challenge, and it's a safety issue - Mac is absolutely not
invisible when biking wearing them.

I couldn't find material to duplicate the remaining horn, so I will be
attempting to make a matched set out of this blue, shiny, Umbro-shorts
kind of fabric.

I'm using scrap fabric from the Facebook crafty altruism meme to
figure out the pattern, then I'll be cutting, sewing and stuffing the
horns. Lastly, they'll get industrial-strength Velcro on the bottom.
