As well as the two couch covers I use two flannel cot sheets as drapes - they wash like a dream. If I think they may feel a bit cool, I cover the sheets with either a cot blanket or a regular blanket.
(I don't use paper roll - I change the top couch cover & sheets after every client -however, if I am seeing a client for intensive treatments, I keep the cover and sheets, in a large archive box in the treatment room - I don't use oils so am happy to reuse their sheets for a few days)
