I use clear, heavy duty shower curtains strung up with rope. I have 2 more bands of rope in the middle and near the bottom. My run at it’s tallest is 7 feet so the shower curtains work well and I can leave plenty of space for ventilation. They get folded and put away for the summer and are easy to install and remove. And they come with metal grommets. I do an overlapping thread so there’s no gap between the sections.
