Quality sheets here in Canada can cost around $200 and above, so naturally we don't buy new ones until we need them.Originally Posted by strange_wings
I have a very thick queen - I can't afford to buy lots of sheets for it or replace comforters twice a year. The sheets themselves usually cost around $50 (or $70..) and any comforter is around the same.
That said, I have a couple of regular sets and a flannel set. One comforter for the time being. Sheets and blankets get washed weekly.
I use home made quilts that my mom made for warmth but do buy a new (read cheap) comforter every couple years to freshen up the bedroom.
I also use pillow covers under the pillow cases and they get washed every week with the sheets. I wash the mattress cover about every 2-3 weeks and vacuum the mattress every couple months. We turn the mattress 4 times per year.
