I added a round of sc in black to the outside. Also, instead of doing 3 sc in the corners of the final pattern round, I did sc ch sc.
It took a few rounds for me to get used to carrying the second color, but I did eventually get it. The chart she posted on the pattern site for round 2 was a life saver! I don't know that I would have gotten it right otherwise.
