I usually do 3 loads of laundry back to back. And I try to make every minute count. Here's the way I do it - do you have any tricks?
Carry all laundry to the laundry room.
Start running warm water in washer and add laundry detergent.
Sort clothes into piles - for us it's usually lights, darks and reds/browns
Change water temperature to cold (for everything but whites)
Add first load to washer.
Here's where I cut down the most time - between loads.
First move wet clothes to dryer, but don't start the dryer.
Start running warm water with detergent in the washer for load #2.
Then add a drying sheet to the dryer, check the dryer filter and push start.
Then change your washer temperature to cold and add your clothes.
I know it only cuts out a few minutes, but every minute counts in my house!! This way there's no standing around waiting for water to fill between loads and I don't get sidetracked on another task FORGETTING to add the laundry!
