BTW, I think on the Snipe there was a difference between the horizontal lacing (which looks in the datafile photos to be the V-shape we'll all trying to replicate here) and the style of the vertical lacing. The vertical lacing looks like two strands of interweaving "thread" that forms a sort of helix patterns. This might have been done around hooks of some kind.

The other observation is that the stitching/lacing really does just look like a somewhat jagged line from normal viewing distances. We don't want to be creating the WWI modeling equivalent of the 1/4" wide "panel lines" which some WWII models might imply about the full scale.

On my 1:6 scale Snipe I'd imagine that the lacing shouldn't actually be much more than about 1/8" to maybe 3/16" wide (from top row of eyelets to the bottom row). That's tough to do when the eyelets themselves are 1/16" wide.
