When we finish the laundry, I sort the bright towels into one pile, and the neutrals into another pile, and simply deliver them to their respective bathroom. This may sound silly, but to me it seemed overwhelming to have to even gather or inventory the information concerning how many towels or washcloths might be currently existing in each bathroom. The bathrooms are both heavily trafficked so the only thing that really matters is that each one has a nice stack at all times.
With an ADHD brain, I really need to work to simplify life in ways like this, in order to free up RAM for more important tasks. Running up and down the stairs and remembering which bathroom needs what is antithetical to that goal.
So there. I had to really think about what bathroom to put the white towels in, but who in their right mind gives small children white towels to use? As such, in our home, the whites go with the neutrals 🙂
