Bike Helmet Ear Warmers

It doesn't get very cold out here in Houston more than once or twice a year.  That being said, folks around these parts aren't used to it.  Even those originally from normal places with snow and sleet find their blood thins after a short period of time.  I decided that justified knitting up some bicycle helmet ear-warmers for an avid cyclist at work.  It was pretty quick, but I recommend anybody planning to knit them, just do so in the round.  Sew the things up was the least fun bit.
