ps
lets assume that the pocket is 9 guy
(on front - with or without text)
so all these are the backs..
..even though jeff said one side only...

**
id reccommend making an embroidered c9guy
that could be stiched on black or white shirts / front
have url printed small
then on back - do something cool
OR - have c9 guy embroidered on back centered to neckline - with url
and have something cool on front
