Elongated stiches/drop-stitch

I have seen others do the elongated/drop-stitch, but they either don’t wrap the first stitch or the last stitch of the row. I don’t know which it is. When I have tried it wrapping the stitches at the beginning and the end it just doesn’t come out right. Does anyone have a suggestion for me?

Amy has instructions for an elongated stitch scarf here. There are some accompanying videos, so maybe that’ll help.
