Alternative for contractor bags

The norm during construction phase seems to be to cover windows with black contractor garbage bags. It makes good sense. It's practical - serves the purpose. But the thing is I'm sick of 'em. And I was given a great little simple sewing machine. And this is something I can do rather than work on the mess I've made of another project. So, for a few days, I'm making curtains. Though they'll eventually be replaced, we may actually keep these little things for a while. My contribution of the moment.
