I agree with the above. Selvedge stitch looks lovely on a scarf, but it has to be in conjunction with a garter or seed stitch edge. The garter or seed stitch prevents the rolling, and if you slip the first stitch as if to purl and knit the last stitch on every row, you get a nicely finished edge for your scarf.
I usually make an edge of 5 knit stitches or 5 seed stitches at the beginning and end of every row.
