If you're trying to keep the sun out of your eyes, this template is for you!  Apologies for the pictures;  hadn't planned to offer this until I filmed an instructional video.  But this is easy enough you probably won't need one!  

Make this with your favorite sports team fabric, bandana fabric or even the sticky back fun foam where you simply peel off and press on your favorite fabric. 

The visor can be finished off in several ways around your head or even attached to your glasses with no strap. 

Check it out in my "Winner Designs Projects" video. I'm showing it from 28:19 to 29:21.
