... do you follow the washing instructions? I was thinking of buying one from John Lewis with my Xmas gift voucher. However the instructions say it needs to be "cool washed ... using a specialist silk liquid detergent". Sounds like a faff as it would need to be washed separately from the rest of the bedding (which I wash at either 30 or 40 degrees depending on whether my dedication to the planet outweighs my dust allergy tolerance or vice versa).
