I just did a scarf with a seed stitch border, and I treated the first and last stitches as selvedge stitches. I slipped the first and knit the last. When there was a row where the second stitch on the needle was a purl, I brought the yarn behind the right needle and between the two needles to purl the second stitch. It made a nice edge.
