I had the same problem, I tried hanging a towel on to see, but no good. I had an awning side made that slides into the groove in the awning roller and goes almost the whole way down the side. It has brass eyelets in the bottom, 5 of them, that I use small bungee loops t peg it to the ground and had a window pit into the middle. I went to a sailmaker who made it up in a few days and charged a fraction of the 'off the peg' ones.
