Here isa small part
of another chart KEY that I color-coded...and of course, color-coded the chart symbols to match! I would have GONE STARK RAVING MAD if I'd tried to knit from this chart in black-and-white. And also, this sweater would have been IMPOSSIBLE to knit in a line-by-line, word-for-word format. The pattern would have been 50 pages long!
Here's just a small part
of the chart:
I wrote the numbers 4, 5, 6 in the symbols myself so that I could easily glance
at the chart symbol
and know exactly how many stitches were involved in the cable. This is all about advance preparation. The knitting sailed along, no glitches.
