Disco,
When I first started training, I used a circle of strong Bonsai wire and merely attached it to the branches. Then trained subsequent branches to the circle. Worked pretty good.

I was thinking of just using some sticks/pvc pipe, zip ties and 2x2 sheet of white barrier fence mesh as the trellis. My friend is using this orange barrier fence mesh for his trellis and that shit hurts my eyes...
