it's not a bad idea, but somehow i picture a bunch of hipster dudes showing off their new shades.
"cool shades bro"
"yeah, thanks and guess what - the frame is made of used skateboards"
"whoaa thats so cool, he bob check out steve's shades they are made from skateboards"
"really? let me see.... yeah,cool shades bro"
the point is, i wouldn't wear them.
