Depending on how big some of the pieces are, sometimes I don't put them in the dryer. Another thing I've noticed is that if they're not ironed they take up even more space because they don't want to lay down as flat. There's no RIGHT way to do this. I'm a little lazier than some. I would just refold and stuff. Half the fun of starting a new project is pawing through your stash and rediscovering something you forgot you had.
