ANYTHING that simplifies laundry (and gives kids a shot at more responsibility) is boss. From Cheryl:
When my children were little, I used a permanent marker to color code the back-neck labels in their clothes. If a garment was cold wash, I placed a blue mark on the label. If it was warm wash, I placed a red mark. The kids could sort the laundry into cold and warm piles in a hurry even if they couldn't read. They got lots of practice with getting the laundry washed while they were still at home, and I really appreciated their help.
