We have a linen closet that for a time in my childhood was emptied out and made to serve as the “Nintendo room”, containing an NES hooked up to an old Commodore 64 monitor. I still associate that fabric/crafty smell with 8-bit gaming.
I also love the smell of sun soaked dog fur.
There’s a soecific air freshener that my parents use at their house. They only use it during winter mainly so everytime I smell that, paired with the warm lighting of their lamps, and the quietness of the snow outside. It always gives me a sense of calm that I can’t explain.
