I would pre drill all the holes at each end of each run, then insert the preferably pre colored rigging line, be it mono or elastic, into the hole and secure with a tiny drop of CA. Elastic installs tight and mono will shrink and tighten right up if you expose it to heat from a hot wire or an adjustable voltage soldering iron. Add turnbuckles out of a small drop of white glue, partially dried and applied with a toothpick or thin wire so it will hold an elongated shape on the rigging wire. Paint steel or brass when dry. Fake glue turnbuckles are closer to scale in 1/48 than anything you can actually manipulate or poke rigging through. They are noticeable as turnbuckles on my 1/48 models, but you really have to squint hard to tell they are glue blobs.
