I've being doing a bit of designing as of late and want to print off different designs onto shirts and jumpers. Doing some googling for printers in Sydney reveals either a minimum run of 15 each design, or a single will cost $60.
To be truthful, this is sort of a test to see if I like my designs on a shirt or jumper and deciding whether or not to open a small online shop.
Hey man, you can try http://www.theprintbar.com they do one off prints for $20... I'm a painter and no one wants to buy a $400 painting but I sell my paintings on t shirts to people and the quality of their prints are really good... I just take photo's of my art and they print it for me...
