Drop cloth curtains: I have a total of 5 of these curtains on my patio! The drop cloths were less than 10 dollars a piece at Home Depot. (Remember, Home Depot drop cloths do NOT have seams down the middle, Lowe’s drop cloths do.)
This looks like a great idea except: Is that a canvas drop cloth? imagine how fast it'd collapse after rain. That said, in central coastal California, in the summer, it'd be fine ... just take it down from October to April. And I think I'd use something else for poles, bamboo or other wood -- "Create your own shade with PVC poles, flower pots and a painter's drop cloth!"
