Selvedge question

I am new to the website and I was wondering if anyone could help me with selvedge edges. What is the best type of edge to keep stockinette stitch from rolling. I thought I tried everything but it still rolls. I am making scarves and I don’t think it looks right to roll on the edges.

This is what I just did on a hat. Knit 3 rows, Purl 1 row, Knit 4 rows, Purl 1 row. I folded the edge under at the first purl row and seamed it in place. It makes a really nice, simple hem, and no curling!

A selvedge won’t keep stockinette from rolling, but a garter st border of 3 sts or so around all sides should do the trick.

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.
