This week, you're not allowed to lift your metaphorical pen off your figurative paper. Show us what you can do with one unbroken line. The subject matter is entirely up to you (within our usual Derby rules), but you have to follow these rules:
Everything in your design should be part of the same continuous line. We should only be able to see two ends to your line. Any other line endings sticking out somewhere will be cause for rejection. And no autonomous little design elements away from the main one. Your continuous line should render everything on the shirt.
No retracing the same path. The line should always be distinct from itself, if that makes sense. Don't fill in a space and try to tell us it's just one line that overlaps itself. Don't try multiple line endings on the grounds that the line turns back on itself.
One color only. No changing the color mid-line or using gradients.
Text is permitted as long as the treatment meets all the rules above. If you can draw text with one unbroken line with no retracing, knock yourself out.
Moderating this Derby might involve some judgment calls on our part, so if your design even comes close to breaking any of these rules, back away or risk rejection.
