Hey, I recently started knitting myself, I'm currently about half way through knitting my first jumper from a pattern (I thought I'd finished the back this evening but then I measured it against myself and it's not quite long enough, so I'm going to have to undo all my casting off to add a few more rows

).
I'm interested to know how much planning goes into the designs on your things, do you plan out every stitch in advance or go in with a basic idea but largely make it up as you go? I'd quite like to try something like this myself, although I haven't tried knitting pictures onto anything yet.
I especially like your world of goo one, it's subtle enough that to someone who hadn't played the game it would still just look like a really good design.
