I do mom's laundry and they still misplaced 3 complete outfits. I am trying to label all the clothes, but the labels came off. I may not have had the iron hot enough or on long enough. I ordered more and will try a hotter setting.
At both facilities my mother has been in the labels were placed on by the staff. The present one has them on so strongly that I can't even lift them slightly to see the label underneath if I am trying to check a brand or size. I would inquire if the facility has a method they recommend or possibly use. You could consider a magic marker. At least that can't fall off. Just don't put the room number in case it changes.
