If you cast on provisionally and then knit from there, you'll still have the other edge being flat, right? The one you finish knitting the first side on?
It starts pointy and ends flat for the center seam, right? If you pick up the pointy part, won't the center seam section still be flat?
I started this scarf but didn't like the yarn I used, so never got to where I'd have to seam.
