Traveler had a bed prop with a blanket as one of the Bbay club downloads at one point, you may want to check and see if it's available in one of the "retro" sale packs... the blanket wasn't posable, or even have many morphs in it, but you could always make some of your own... you can see a picture of the bed itself in my gallery image "Bedroom Boredom" (well part of the bed anyway -- and fair warning the image has nudity in it)
