would this bother you?

Of the knits I'm currently working on, I've recently been most disciplined about a baby cardigan. I donated a custom baby sweater to the Public Interest auction at school last spring and was amazed at how high the bids went. (It might have helped that I had a handful of friends who needed baby gifts for newborn relatives and kept pushing the bidding...) I had a whole plan about how quickly I would knit the sweater, and, in consultation with the auction winner, picked out the yarn colors and the oh-so-popular Baby Surprise Jacket pattern.

And then. It turned out ugly. Really ugly. So ugly I didn't even bother with pictures before frogging it. So ugly that it disheartened me. So ugly that when the winner said, "Well, the baby won't need a sweater for a while" I took that to heart and shoved the yarn in a bag for six months. But the baby lives in New York, and the Northeast is getting darn close to sweater weather, so I decided at the beginning of the month that I couldn't ignore it any longer. Originally, I thought that I would reknit the BSJ, since I'm pretty sure that I learned enough from the uglyness to produce a cute one. But I then got nervous that I'd go through all that garter stitch and it would still be ugly, so I picked a pattern from the reliable Natural Knits for Baby and Moms and started in. (I'm hoping the auction recipient will be so happy to see a finished sweater that she will forget that it's not the BSJ.)

There are a few things about the pattern (ravelry link) that I don't get, however. One is why you'd use three-needle bind-off at the shoulder seams when you could kitchener. I just don't see why you'd want a really obvious shoulder seam since the cardigan isn't heavy enough to need a distinct seam. And aren't you supposed to strive for seamless in baby knits? So, thinking how smart and knitterly I was, I kitchener stitched to my heart's content and gazed upon the beautiful results of my grafting.

And then. Hmmm.... As you can see from the top picture, the pattern is four-row stripes of blue with alternating two-row stripes of brown and green. But, since I didn't think too hard before starting my kitchener stitch, the shoulder seam stripe is a three-row stripe of brown. (The top and bottom row were the live stitches that I grafted together and the middle row is the kitchener stitch row of grafting.) So the question is: how much should this bother me? On the one hand, when you look at it from the top, it's clearly wrong. On the other hand, when you look at it from the front or the back, doesn't it probably look better to have a little extra brown up at the shoulder's bend? So it might even be good that there are three rows of brown up there, right? Or is that just me rationalizing a silly mistake?
It probably wouldn't take me that long to fix, but I guess I'm a little tired of frogging this yarn. Yet I also feel like there's no point in rushing through a mistake, considering that I'm already embarrassingly late in producing this. (Also, I'm knitting the two-year-old size, so it won't fit the baby for at least another year, so there's no worry that it will outgrow the cardigan anytime soon.) What do you all think? Careless mistake or serendipidous solution?
