Print out the chart and note that, on the right-hand side of the page, underneath the right-hand chart, is a Key of symbols used in the chart. Note each symbol, and again make sure that you're comfortable making each kind of stitch the symbols refer to (they should be either regular K/P stitches or the special stitches we discussed earlier; the Key isn't where we expect to find surprises, but it can happen).
If you haven't read charts before, that's a whole 'nother thing.
The general idea of charts is that they start with Row 1, Stitch 1, at the bottom right-hand corner of the chart and move up, as the knitting itself builds up.
Odd-numbered rows (often referred to as "RS" or right-side) are read right to left; even-numbered rows--when shown at all--are read left to right. Many charts print the even row numbers on the left side of the chart, but this one doesn't do that for you. sigh It's a nice reminder that you're working on the WS, or wrong side, of the fabric and that you should be reading the chart from left to right. (I'm working three charted patterns right now, and I'm very happy that each one of them has printed the even row numbers on the left!)
