I also screwed up the stitch count in my spreadsheet that I use for determining transitions because of an error in the pattern that I didn't catch until I was knitting that section. The pattern says to repeat the first border chart 80 times, but in fact you repeat it 160 times - there are 6 rows in that chart, but you're only taking care of 3 stitches of the body with each repeat. I doubled the rows of the original first border chart (12 rows as opposed to 6), so my border chart gets repeated 80 times. In the end it didn't really matter because it wouldn't have changed when I did my transitions between skeins.
