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.
Greasy pepperoni pizza with a hint of cardboard, live rosemary, the first few times smelling rain and dirt after winter, cold winter air, green tea, so many things
