Fast re-cap on the LAST time we got shirts....
The topic ambled along aimlessly like a shopping cart full of cement, crashing and banging in every direction. Then Adam submitted art to the manufacturer after much debate. Because of the small run, they were a bit pricey ( $12-15 if I remember correctly) Then there were problems with the artwork. The image was too blurred...too small...people complained. Adam was caught in the middle.
My suggestion is this: Whomever really wants shirts should step-up and just create artwork and POST IT instead of waiting for someone else to do it.
Wait & see is a bad idea....
