There is an error in the written instructions, which direct you to knit the charts in the wrong order on the WS rows. Instead of working the charts A, B, C on both side, work charts C, B, A on the way back on the WS.

Also, there is an error in both the written and charted instructions for row 27 of chart C.

I think this is what should be there: (K1, k2tog, yo) three times, (k1, yo, ssk) twice, k2tog, yo, k8

Aside from those things, the pattern is simple and nice, but I wish that either chart A was a repeat of four rows or chart C was a chart of 20 or 30 rows. Having one chart be 10 rows and one be 28 rows makes it a little harder to keep track of them in my head. It would be easier to track if one was a multiple of the other.
