similar
Hey guys,
I did something similar back when KERA started. I just took the KERA logo, saved it to my computer as a picture file, then went to wally world and bought some t-shirt iron on paper for ink jet printers. Printed out the logo and ironed it on my own shirt - worked great - and simple to do. Maybe it's not of the highest quality that some may want but the shirt/iron on has held up after washings and only did the typical fading over time.
As far as going to a print shop, graphics shop, t-shirt shop, sign shop, etc - nowadays, they are all computerized. You can take just about any image on a disk to them or maybe even just email it to them and they can take it from there. That's how I got some stickers made for a zx-9 I rebuilt years ago.
Hope that helps a little. Later.
