The charts are mislabeled in the print issue: Cable Chart A is Cable Chart B and vice versa. If you're working from the Ravelry download, the error has been fixed. If you're working from the print issue, you will need to work Chart B on the front yoke and Chart A on the back.
The first row of the Back Yoke section should read as follows. Changes are noted in red.
Next Row (RS): Work in patt as est to 4 sts before shoulder marker, transfer 39 (39, 38, 40, 41) front yoke sts just worked to waste yarn, join new ball of yarn and BO 5 sts (rm for shoulder when you reach it), work in patt to end of row—42 (42, 41, 43, 44) sts rem for back yoke.
River Rocks Scarf
There is an error in the instructions for the Two Color Italian bind off. The bind off should be worked as follows:
Step 1: With DC, leave tail 5 times longer than width of scarf. Thread tail onto tapestry needle.
Step 2: Insert needle purl-wise into first st and pull yarn through. Then insert needle from back to front between first two sts and through second st knit-wise. Pull yarn through.
Step 3: Insert needle knit-wise into first st, pull yarn through, and take st off needle. Then insert needle purl-wise through second st, pulling yarn through. Leave st on needle.
Step 4: Insert needle purl-wise into first st, pull yarn through, and take st off needle. Insert needle from back to front between next 2 sts and through second st knitwise. Pull yarn through.
Rep Steps 3 and 4 until all sts are removed from knitting needle.
