What bothers me about the instructions is the way the direction is worded. Maybe I'm reading too much into it but it says to repeat round 1 and progress through the chart. Just reading this cold, I'm thinking by telling you to repeat, it is actually telling you to do the second line rather than doing line 1 again and then the subsequent lines. Does that make any sense??? How would that affect the number of stitches in conjunction with the patterning?
However, I agree with Ingrid. Maybe you should try to follow the knitting rather than the chart. Usually in a repetitious pattern, it is simply a matter of knitting and purling where it is obvious.
I've never ordered a pattern from Knitpicks before. Do that have a customer support line? Could there be a mistake in the pattern? These companies are not infallible.
What yarn are you using? I really loved this pattern. Does it give any sizing other than the length? It looks pretty full, so I'm hoping it will fit me.
