The main point of a DIY lattice privacy screen is to grow plants up it. As such, it’d be ideal for a balcony or for hiding a hot tub from view.
You can simply grow tall plants in pots to shelter whatever you’re trying to cover. Big, bushy plants like bamboo work great.
The advantage of this DIY privacy screen is that you can fold it up when not in use.
The easiest things to use for a DIY privacy fence are bamboo canes or reeds. They’re inexpensive and easy to fix together into whatever shape, pattern and size you need.
You’ll need fairly straight branches, but a bit of bend in them will add character. For even better results, use driftwood gathered from a beach.
