That is a picture of two containers of play-dough in my completed wash load.
I did eventually find the thing I dreaded: a lid with no container, followed by an open container of green play-dough Miraculously, that green play-dough adversely affected a mere two items of relatively inconsequential laundry: a Hattie sock, and a pair of Cy's underwear.
The events leading up to this strange laundry occurrence transpired while I was getting ready for my run this morning. Hattie occupied herself by removing play-dough containers from the craft closet, and, evidently, throwing them into my basket of waiting laundry. I guess I will be checking my laundry baskets before dumping them in the washing machine from now on.
