I do my bedding once a week always have done since i started charging my bed.
I do my son's once everyother week. I alternate their changes so I don't have masses of bedding everywhere.
My mum told me to fold the bedding on the iron board flat whilst you iron other stuff and periodically move it round the board. It all ironed then and your not struggling trying to do it.
Weekly. Sometimes it goes on to the ironing pile (our cleaner does it) and others not. We just got new seersucker bedding which doesn’t need it and it’s a game changer!
In the hot summer months or if either of us are poorly it gets done more often.
Once a week here too. If it's hot during the summer, then possibly twice a week.
I never iron it. My husband does it because he likes it ironed, so there's only one way that's going to happen
I know a guy who doesn't iron his clothes but he always irons his pillow cases because he can't stand them crinkled. I have to say I admire his priorities.
