I treated myself to a set of pure linen bed sheets for a big Birthday 6 years ago. Holes appeared in the flat sheet by about 2 years of on/off use. I complained to the manufacturer who told me it was my fault for laundering in Persil (optical brighteners) not Ecover and gave me a voucher for a half price replacement. Eventually bought a replacement with voucher and a bottle of Ecover. Next, I confusingly found my feet in a hole in the duvet cover. Contacted the company who offered 30% discount on replacement. Nah, that's throwing good money after bad. Now I find the second sheet is holey. So that's my adventure in linen over, £400 and 6 years later. I expected they would outlive me, like the striped flanelette sheets my Nana bought in the 1950s that still have for emergencies. Maybe I'll switch to them. The bottle of Ecover has lasted longer 🤣
