Linny, no, that is not necessary. Yours is fresh and neat and tidy. I generally don't wash them until they need it. Yours will not have any markings on it or any pet or smoke in it either. DH has quit smoking!! He has been cig free since December 31. I am so overjoyed. He is sleeping better and breathing better already. Amazing what those things will do to ya. I am still working on that king on the frame, but hoping to finish yours this weekend and mail on Monday. At least that is my goal. Will let you know.
