Back and forth
Can you tell I'm having fun?
This is one of those patterns, like Clapotis, that is pure genius in its simplicity (I've already figured out how to tell exactly what to do next just by looking at the work, so I can put it down and pick it up at will, and until I get to the final decrease section, I can take it with me wherever I go without having to worry about remembering to take or needing to endlessly check the pattern), and yet somehow continues to be endlessly entertaining. This was all I was planning on doing today before letting myself move on to something else (I usually get bored easily, and so I keep a variety of projects going so I can keep making progress), but I want to keep working on it, so I'll probably get at least one more repeat in today.
Well, now that I've had my fun with revealing the way the pattern is developing and you all can see what's going on (and since allison asked :) ...
The pattern is Kureopatora's Snake, by Kim at String or Nothing. If you've never visited her blog before, I highly recommend checking out her Reference Shelf in the sidebar. She's an amazing source of all kinds of technical details and analysis. Well worth reading on a regular basis.
