Can i part dry clothes in a tumble dryer without them shrinking? I ask because none of my clothes are drying well at the moment (too cold to dry clothes but not cold enough to put heating on) and I've had to re-wash some because they smell stale. And I've only got two pairs of trousers at the moment because I'm pg and have only bought two pairs of maternity trousers so far and one of them is always dirty/damp trying to dry!
