If it was up to my husband, it would once a month at best! But I like to change them once a week – if I had more time I would change them every 3-4 days but my washing machine wouldn’t be able to cope with it!
I was not as fussy about it when I was younger but as I get older and appreciate my sleep more, I like to be in a freshly made bed!
Ii change mine nd pillowcases every week nd duvet cover every 1 to 2 wks if warm weather like we hav had I change more often.wen I go away always hav clean bed stuff on to come bk 2 nd xmas eve put clean bed stuff on,my mum always did this so spose got frm her. 🙂
