Joseph and Christine,
Thank you both for your helpful responses. I have a layout that will work well. In considering the question of whether or not a single strand will be effective enough, I have realized that it would be quite easy to add another strand. Hence, my new and hopefully final question:
If I were to run a 2nd hot wire next to the first, either directly above/below or staggered for the 3D effect, should I:
A) run the 2 hot wires in a giant connected loop and use one long piece of wire?
B) run the 2 wires connected at one end and apart at the other end? (a halfway connected loop)
C) run 2 separate unconnected wires and hook them up to the energizer at 2 connection points?
That is to say, will the connection be better if the hot wire is one continuous, uncut piece? Thank you!
