Pre-MN I didn't know these existed, now I'm saving up for either [[http://www.laredoute.co.uk/100-pre-washed-linen-duvet-cover-in-5-colours.htm?ProductId=324157550&t=6 these]] or [[http://www.laredoute.co.uk/pure-linen-duvet-cover.htm?ProductId=324182457&t=6 these?]] What do you think? Are these a good buy or could I buy better quality elsewhere? Also, does anyone know what difference pre-washed makes? Are they softer? TIA
