Bob, that's EXACTLY what I decided after spending over an hour single-lacing the piece I've prepared. I'm not sure if the eyelets would take the stress of a second thread -- and I'm not sure I'm up for another hour of lacing!
But perhaps most importantly at 1/6 scale the double-lacing looks just a bit too heavy. If I were doing a 1/4 scale Snipe, I'd definitely do the double as I really like the way it looks.
I'll post some photos of the result on my Snipe thread.
