We have been line-drying our clothes all summer, and I've had a major problem with how they've turned out when dry: super stiff! I decided today to find a solution. Turns out, 1/2 to 3/4 cup vinegar will keep them from getting stiff and because it dries outside, the smell goes away. Thank goodness for that because I completely dislike the smell of vinegar.
Since it is raining today, we get to put up a line in the basement for the cloth diapers to dry. Turns out that I had forgotten to bring in the clothes from outside before work last night and they're getting an extra rinse. It's all good. They can dry tomorrow.
