It's simple enough.
Hang some yarn from one stable object to another (in my case I used a filing cabinet handle to a door handle). If it is a long distance (as was needed for my mountain of laundry) loop the yarn around a few chairs in the middle.
I pulled out my clothespins and told Helen to hang the laundry to "dry" She loved playing with the clothespins. I told her she could only hang laundry from a certain basket (the unfolded stuff). As items became "dry" I took them off and folded them creating new room for her to hang more up.
And we both got the laundry done! Wahoo!
