If you can't hang the laundry outside, hang it inside. Okay, so that's not so extreme. But if you don't have a place for it inside, put it on wire hangers and hang those from doorways, from dresser knobs, from the backs of chairs, from lamp shades... wherever a hanger will fit. Of course you don't want to weight a lamp so it turns over or cause damage to anything. Put heavier items in the doorways.
