Most of you know that I like to do things as all-natural as possible, including my laundry. I use only baking soda and vinegar to wash my clothes. A few months ago, I purchased a set of wool dryer balls. I LOVE THEM! The help separate the clothes, while tumbling in the dryer, in order to aid in a faster drying cycle. I use two per cycle and put about 3 or 4 drops of essential oils on them each time I do a load. I highly recommend them, and they can be used again and again and again!
