I just ordered a Large Orchid one with silver snaps. I got Grace a Large and I hope it won't be too big. She is right at the limit on measurements for the Med and at the small end on the measuremants for the Large. I went with the Large...I hope it isn't too big!! I've never bought a $30 cover before. I really want to like wool...and I like that this is machine washable!! Do you really put it in the machine? Is the fit good? Does it work well overnight? Thanks Mamas!!
