Working them through the back will tighten them up a bit and it's certainly worth a try. If the edge is being seamed, though, a loose edge or slipped stitch won't really show. It won't hinder picking up stitches, either.
To avoid a loose edge stitch, I find that holding the yarn tight and working the second and third stitches tightly tends to keep the first stitch tighter.
