I've found that running them in the drier 20 min after hanging them in the sun, helps. They are usually slightly damp in the middle (I use mostly prefolds). I've also found that hanging them when its windy helps (they get to move some and end up less stiff). Or hanging two
But what seems to really help is putting them in the drier for 20 minutes (again slightly damp in the middle) with a tennis ball. The bouncing of the ball seems to fluff them. I also use this to fluff our comforters!
Hope that helps someone.
