... and laundry is a biggie.
Especially with three girls. The older two produce mounds of dirty clothes. Previous solutions were individual laundry baskets and then later, one community basket. Baskets, stairs and shorter limbs only complicate the problem of getting the dirty laundry to the washing machine in the basement.
My newest idea was to use laundry bags. Once it's full, they can just roll the bag down the two sets of stairs and drag it to the washing machine. And then once their clothes are dry, reverse the process. I had a couple of bags on hand, so no big deal. Until wash day came and I realized that I needed spare bags for their newly dirty clothes while the others are washing.
