Fortnightly is fine for most people, including me, though more often in summer when it is hot.
No laundrette anywhere near.
I don’t have a tumble dryer, partly as I don’t have room, but also on principle.
I can’t dry anything over the banister or over the back of a chair, as they are stained wood, so would stain the item. Ok for airing though. I have a non- heated rack for drying indoors.
My daughter has the old-style rack from the ceiling over her Aga.
