We're setting up a webshop where people from all around the world will be able to order t-shirts, pins, cups and whatever they like. So if you got any design/image suggestions you want on the objects just post them here or send them to me through PM.
There's a recommended 100 pixels per centimeter. That's quite a lot, but perhaps it'll be possible to see if the images are ok on-screen (when zoomed up or similar). Even the TKC logo needs some quality boost if we're to make big logos.
