More simple running stitching makes for a boring photo, but it gets things done!
A question in this week about the lines of stitching often seen on the outside of medieval re-enactors' clothing. It's not decorative, it's the reverse of the seam being stitched down.
Whether you fold an extra time to encase the raw edge, or not, you will see a faint line on the good side. Two lines indicate wool or a thicker fabric where the seam is opened and laid flat before stitching down.

My photo shows the seam in progress, unironed, with the stitching almost invisible from the good side. Stitching seams down affects the drape of the garment, as overlocked seams encourage the fabric to fold inwards along the seams whereas stitched down seams encourage the fabric to continue the flow of the fabric.
Later this week, stitching a hem! Who knew sewing was THIS exciting?!
