I am going into my 3rd month of hosting, and have learned so much from this site and from experience about bedding! I was so worried my all white sheets and towels would stain, and they have not. A few accent hand towels bleached out from whitening toothpaste, but that is all!
One thing I have learned is the value of nice blankets. I invested in some thinner, upscale "quilts" in all-over nuetral colors like white and tan pale paisleys, and then in some high end cotton blankets in tans and teals. This allows me to make up the bed and fold down the quilts and sheets to show off the blankets. Guests have commented how nice it looks and how easy it is to get cooled down or warmed up at night. I just despise fleece blankets! Stretchy, hot and ugly to me.
Pillow covers have become de riguer for me as well.
What I would do over is to have bought two platform beds instead of one. The traditional bed requires a dust ruffle and is a hastle to make, harder to clean under and makes the room look busier.
