I have a long, narrow ground floor patio space that I never use for a number of reasons. One is zero privacy. I used wood clamps to successfully hang christmas decorations this holiday and I want to use them to create a six foot curtain on the far end of the patio. In addition, I've always had these metal chairs and the cushions are covered in dust because of all the dust this space accummulates. So I'd like a seating/storage solution where I can keep the cushions clean while they are not being used. I also love plants and a cozy/textured feeling. But I don't want to have to drill into the outside of the building or brick. Renter friendly ideas please. My budget is around $400-600 for this space. Thanks!
