Rarely to never, because our clothesline is in a stupid ass position where its in full shade by 930am every day from about April to October, and it pretty much rains during the day at some point from November to March so I've just given up. We also don't have the space for clothes horses inside and the only place for them outside means that every man and his dog can see all our washing. I used to put small things on a clothes horse on the patio until asswipes at DH's work started commenting about my underwear. Our power bill was still 15% below the average for the HLB so I figure its not costing us much more to put things in the dryer.
