It's been pointed out that there's a symbol in the chart which is not in the legend. The symbol, a simple vertical line, should be read as 'knit.' I was using new charting software and was still getting used to all the symbol options; I thought I'd cleaned up the chart but that symbol slipped right by me.
I'll try to get a corrected chart into the pattern listing and the download, but in the meantime, that symbol means 'knit.'
I also had a question about the direction of the ssk and k2togs; the correspondent wanted to know if I had misplaced the symbols in the chart. The answer is no; the chart reflects what I actually knitted and what you see in the photo.
