Just a quick note to share my attempt to resolve the towel confusion situation.
If this doesn't help, I will just throw all the towels away and buy white for everyone!
Towel Storage for Dummies!
BTW, I have the same system for towels as bed linen - two sets, one on, one off. I trained my family to rehang their towels years ago by fining them 50 cents for every towel found lurking in bedrooms or on the bathroom floor. It is now a family joke, but it used to reap a fortune for our Kris Kringle jar!
