people are interested, there are a good handful of people willing to preorder (who may be the only people to get shirts, depending on the quantity)
so things to keep in mind...
i would suggest making 2 versions - a small version or mock up to post here and a larger (300dpi - and to scale) image for printing (most places prefer 300 dpi )
try to keep it 1 color ( so , shirt color

uhmm...
if you want to make a 2 sided shirt, do it to it - but try to make the front stand alone if possible. just incase.
again. not trying to be bossy - just want to help organize this so we can make it happen.
