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.
Almond-scented stuff (not almonds themselves - they have no noticeable smell to me).
Pine forests, the sort with lots of dry pine needles on the ground.
I’ve never been in a pine forest, everything around me is decidedly deciduous. I’m gonna have to find the nearest pine forest and go smell it.
