When you "framed" the elongated stitches with knit stitches, did you just add k1 to the beginning of the row, or did you add another k1 to the end of the row as well? Because if you added a stitch on both edges, you'd end up with k1 at beginning of the row and k2 at the end of the row, which would cause some assymetry. If that's not what happened, then
. It's not a stitch I've ever used, but it seems like it should be symmetrical as long as both edges have the same number of regular k's.
In Amy's instructions for her elongated scarf (in the free patterns section
), her elongated stitch row doesn't have any plain knit stitches at all. I actually think that makes more sense because it seems like using regular knit stitches as your selvage would make the edges short (lengthwise) relative to the body of the scarf, causing puckering.
P.S. You have the same avatar as someone else here -- but I can't for the life of me remember who!
