First of all, thanks to everyone who commented the other day on the progress that I've been making on this charted test-knit pattern. I really loved reading your thoughts about this piece and feeling the support. I double-checked and the charts/pattern is correct so I guess it's me. What I mean to say is that I think it's the way my knitting transitioned from Chart A to Chart B -- because the design is extremely clever (and it truly is!), the piece shifts from a strict triangle slowly to a rectangle.
It might also have something to do with the yarn which is, as Julie once said about another new yarn that had recently joined my stash, a bit crispy.
I've almost completed half of the required repeats of Chart B which will give the scarf its length and then I'll be in the home stretch. For those of you who wrote that blocking will probably smooth out the rough spots, I tend to agree.
