When I sort laundry pre-wash, I sort it out by each person and then by towels and blankets. I usually only get to laundry on the weekends, but it only takes me one day and everyone has enough clothes to last a week anyways. This gives me 5 loads to do. This method makes it easier on me because I fold or hang each load out of the dryer and take it to the right spot. If you want to do laundry during the week, you could give everyone a basket and when it is full then it is time to do wash for them. This way you aren't sorting things out twice. Most of our clothes are colors so if you have a lot of whites you would have to add this load to the list. Please leave me a post as to your speed method for laundry, there is always room for improvement.
