When I want to hold the curtains back to look out on my lanai, I’ve been using an elastic band thingy that came with my mail-order couch. It’s the perfect size, shape, and color.
Just recently, I discovered a way to see even more of the lanai – I hook the elastic band on the curtain rod. It allows me to see the entire lanai. More fun to watch the birds when I feed them, and more light coming into my condo. Nice!
