I’ve got about 6 different bedding levels
Really hot - get the thin sheet out
Quite hot but gets chilly - thin sheet and one of the several blankies
Bit warm - thin duvet
Getting cold - medium duvet
Oh shit it’s cold now - clip them duvets together
Lord have mercy I am freezing - duvet plus super thick heavy blanky
Bed time clothing ranges throughout the year
I also say “duvet” like “dove-ete” and I’m thinking of getting a heated mattress topper
