Lowes and Home Depot have sun shade on a roll. Buy just what you need. Comes in real nice colors and looks real nice when hung up on an RV. Provides privacy while still looking nice and keeps the sun out!
I found the easiest way to attach it to the side of an awning is with clips. The angle of the arm really prevents you from just putting a hook thru the holes of a grommet because depending of the angle you have the awning at the sun shade will slide down
Then pick up a bag of those plastic clips from the tool department and attach the sunshade on the awning arms with the clips. It will stay where you put it.
I have three of them one for each side of my awning and put it up and down in seconds as I need them.
