Having been a hand-cut-only guy, then getting a plotter, I don't see the need to separate into categories. Look at the stuff I did pre-plotter, it's not any worse than what I can do with the plotter, except for perfect circles and text. My Bama discs had perfect text, and the letters were cut by hand.
I understand the argument -- I used to make it! -- but now that I've seen the other side, I know that it still takes plenty of time to get a design right, then get it cut, whether you cut it by hand or by plotter. Still have to weed, still have to mask, and Skinner's right: for multi-colors, you're basically hand-cutting after the first mask anyway.
If you looked in my gallery, and you didn't know better, I bet you wouldn't be able to guess which were by hand and which were by plotter. Especially for a "theme" disc, where you're not gonna get guys just doing circular patterns, we'll all be working hard to do the contest justice.
Can't wait to see how this year goes! The crop of talented dyers has grown substantially this year, so I expect great things from all of you! We don't often throw down like this, so why not BRING IT!?!?!?!
