Let's see the things folks are using for trellises, and, of course, the lovely plants on them!
The pot on the right has Monstera obliqua and some Pothos (Epipremnum,) with WJ (Tradescantia zebrina) around the bottom.
Philodendron 'Micans' on trellis that used to be part of a utility cart. Shelf bent into square shape.
Philo 'Brazil' and Scindapsus, same trellis as above pic.
Philo erubescens vine, piece of chain link fence, bent into U-shape & stuck in pot. 2 Coleus cuttings are deciding if they like it there or not...
Just put this together last week, Callisia fragrans using one of the sides of what was a utility cart as trellis.
