Lattices with larger holes are a bit more common, so you can always use an expandable lattice like this one and add more privacy with real or artificial plants.
A privacy lattice hung from your balcony’s ceiling won’t do a ton. But you could use it as the basis for a larger privacy setup, such as hanging curtains or plants, to create a more contained space.
Freestanding panels are ideal as space dividers or as a flexible privacy option. Unlike other lattices, they obviously don’t need to be fixed to a surface.
If you have a balcony wall rather than a railing, consider using a privacy lattice as a topper. A small expandable lattice is ideal for adding extra height and support for plants.
In some ways, this doesn’t deserve its own entry because you won’t really be using the lattice for privacy. Instead, the plants you grow up it will be doing all the work.
