I use this graphic on all my packaging now adays. It started as a linoleum print and I would print onto every evelope before shipping it out. It would take me forever because spreading ink, printing, leting dry, and then packing shirts is a surprisinly time intensive activity. Plus you need sun to dry the ink but too much sun and all your ink dries before you have time to spread it! Art is fun, but it can really be a pain sometimes. 
 
To fix this, I started screenprinting the graphic onto the packages and figured I might as well print some shirts while I'm at it. 
 
I really like this graphic because it is so positive and simple. So, with that, I hope you, "Have a Great Day!"
