Is that string attached to a nail on that stick? Also I wish they had a closeup so I could see the string as it is looped around. I have a good general idea, but I prefer preciseness. I suppose a little experimentation on my part will give me the entire picture.
I agree about the need for a close-up. Can't really see what she is doing. Just wrapping the string around would cause leaves to fall when the stems dry and shrink.
The sticks are probably what we call "lath," which is what is used by commercial shade growers in Connecticut. (Lath are the sticks used to make plaster walls.) The ends of the lath have slots a couple inches long to which the string is inserted and wrapped at both ends. We use sewing machines that do pretty much what this woman is doing, but although there is no knot made the string is tightly looped around the stems of two leaves at a time. Some leaves always fall off later but not many.
The best way to hang primed tobacco by hand on a lath or any kind of stick is to insert a large sewing needle into each stem, using string that is thin enough to be able to break off by hand. This year I am using very thin wire and pushing it through the stems, then hanging the wire, about 3 feet long, by attaching it to a nail at the ends to poles in the barn.
For hanging whole plants I am just nailing the stalk to crossbeams in the garage.
