Listen, there's nothing wrong with the fact that your kennel's shirts look like they were designed by your GM's "artistic" kintergardener, and don't let anyone try to tell you otherwise.  Just know that other options exist. 

For instance, you could hire I'd Do Norman Cockwell to stock your haberdashery with amazing sh#t.  He was an artistic kintergardener once upon a time, but now he's a professional graphic artist that's been making cool stuff for everyone from MoA2H3 to Wired Magazine since 2004.

Got 50 runners in your kennel? Tell the wanks to pay $2 extra for a shirt that looks sweet.
