Shed to lounge

Hi, I am trying to turn my shed into a lounge but I am having trouble with doing it alone. I have already installed tarpaulin as doors for it but I am having a hard time anchoring it because the wind is not cooperating with me. I think I may have messed up too because when I was looking at it, it looks like it will be a little too short once I roll up the bottom of it to put rods in it. It is really difficult for me to explain these through words and I really think that it would be better if I show pics or come to see it in person.
