Comments: I made a mistake in this pattern, and fixed it half way through - look closely, and you may be able to see it. Basically, I reduced the increased stitches by knitting the 5 stitches together, instead of knitting them together through the back loop as I was supposed to do. You can see how the stitches in the top two rows of, um, "clams" twist slightly to the left rather than to the right. I thought maybe this would affect how well the clams stand out, but I don't think it does.
