Silvia pointed out Nina's cry for help and asked if I could help her out, since I'm working on this shawl. (Which I still wish had, you know, a name. Or at least, a name I could interpret.)
Well, first, I don't read Japanese at all, so I've solely been working from the charts. Which means that, while it's possible the text says differently, I literally started by casting on 7 stitches and then just starting with Row 1 on the chart . . . knit, knit, YO, knit, YO, knit center stitch, YO, knit, YO, knit, knit.
The first chart is pretty self-explanatory . . . just knit straight across each row. The blank squares are stitches that don't exist yet (each row grows by four stitches).
The second chart is actually used 5 times, with one extra repeat section each time. (Currently, I'm on the third repeat.) Then, charts three and four are used one time, each.
Did this help? It's my first Japanese pattern, too, but I find it to be pretty much the same as any other triangular shawl lace chart I've done. There might be something I'm missing out of the text-instructions that I can't read, but . . . everything seems to be going smoothly.
You know, even if I haven't worked on it in a couple of weeks now, poor thing.
