Method for rolled seam stitching at Coaming?

[Douglas Jacobs]

I've searched the videos, the forum, and internet and haven't found any information about how to stitch the seams at the coaming when starting with the coaming and working out to the ends of the kayak.  When I get the nails in place through the holes around the coaming, do I then stitch the seam on the inside and under the coaming before starting the stitching on the outside of the coaming? Should I stitch the seam after stitching the skin to the coaming?  Or should I stitch the seam back to the stern and forward to the bow and end by stitching  under and inside the coaming, or will the skin be tight enough around the coaming that I don't need to worry about stitching the seam under and inside the coaming?

I actually to stitch the fabric together just enough to hold it in place under the coaming. You just have to work out where with the coaming in place.  Do I not show this in one of the videos?
