Does anyone know how I go about adding a flap to my mini gear hammock? ...I think it's called seep? I may be a bit wrong on that. Do I add the flap and then sew down where the suspension is a bit so that it "flaps" down?

I unlashed my mini hammock to see if any better ideas came to me, or if I could pull this off with one the one piece of fabric, and I'm just coming up blank right now. If anyone has links to share, that would be great.
