I recently started doing laundry differently and I love it.
We used to gather all the clothes and sort them by color and then wash them and then sort them again by whose they were and then put them away. I'm not sure why I did it this way but I did. So after watching a particular episode of Jon and Kate plus 8 and seeing how she did laundry I decided I could adapt her method to my family.
Everyone has their own laundry basket (one for each kid, Mark and I share, and 1 for towels). The kids also have a laundry bag in the laundry room. The rule is if you take your clothes off downstairs then put them in your basket. If you take them off upstairs then they go in their own laundry bag. I also have a basket in the laundry room for just towels. On laundry day the kids bring their baskets to the laundry room and dump their bag of laundry in their basket. Then I wash each basket by itself on cold. Each basket is a large load-or close to it. After the load is dried it goes back into the basket and in the case of the kids they take them back downstairs and fold and put their own clothes away.
I still do laundry once a week but this method has saved me time in the sense that I'm not doing the sorting before or after washing. Maybe this wasn't an epiphany to anyone but me, but I'm sure glad I figured it out.
