If your children are still young or if you have a wide selection of clothing, color coordinate the family's wardrobe so that every one wears like colors the same day. At the end of the day, wash everything together. Sort your clothes by whites, darks, levi's and towels, then sort again by category. The reason for this is because it can be very frustrating to pull out a load of socks, undies and T-shirts because you washed a load of whites and now your stuck folding underwear for an hour. If you will toss in a few towels and possible a few white shirts or a white dress, the task will go much quicker.
Diversity makes the task go much quicker.
You may also prefer to sort according to fold or hang categories. You know the little clippy things that you connect a pair of socks. While they may seem time consuming and more trouble than they are worth, consider how much time you spend sorting and searching for socks. Using these little devices will help reduce your laundry chore quite a bit. Now, when you do the laundry, place this card on top of the last pair of undies in the drawer.
