Rayon Blankets

This is just a little warning. I bought a beautiful rayon throw blanket for our guest room, due to all the dust from the construction I had to wash it. Well low and be hold, washing it in the machine caused it to leave little "duck" feathery things all over the rest of the bedding in the machine. Then when I put it in the dryer it over filled the lint trap about 6 times in the time it was in the dryer. I finally had to take it out and let it finish drying on it's own. I made the mistake of not reading the tag and treating it like any other blanket. It should have been washed on the hand wash cycle and then laid flat to dry (yeah who in the world does that with a blanket).
