Before starting the pattern, I definitely had misgivings about a few of the elements, including the garter rib and the faux seam.
I considered nixing both of them in favor of regular 2x2 ribbing and no seam, but then I decided to try something new. By the time I had finished the ribbing, I was pretty happy with it.
Now, I'm maybe halfway through the body stockinette, and I'm sold on the faux seam too. I don't have any problem sewing actual seams, but if I get to the end and want to tighten it up a bit I could still do that.
