How does everyone wash theirs? Mine only just about fits in the washing machine and I’m afraid the weight of it will ruin my machine. Also it’s too heavy to spin so is dripping wet when I take it out, so very heavy to hang on the line. Putting a duvet cover over it doesn’t work for me because, despite the weight of the thing it slips and slides everywhere within and it’s a bloody work out trying to get it back in place. 😮💨
