This is really a BUMMER for you! I know you are 'reading' the pattern right, cuz another Rav knitter says the same thing...no directions for the 'woven' cables at the shoulders and down the back.
No charts either? Could the chart for 'the weaves' be located in the back pages of the magazine? I have a new magazine (Knit n' Style) and it plunks all charts in the back of the magazine. Just a little notation about where to find it, too.
I cannot imagine a magazine forgetting to include the cable chart, nor the designer failing to furnish a cable chart! Either scenario is unthinkable!
Additionally, the other Rav knitter says there were no directions for the neck shaping either! What a funky magazine! Who proofreads over there at Creative Knitting? Remind me to FORGET picking up a copy of that magazine, EVER.
posted a few notes about how to work the 'weaves', aka basketweaves! But you are really on your own for putting that into play!
