My tv or tablet while I grt comfy on the couch. Wearing a house coat and having some ginger snaps and a pumkin spice latte, heavy snowfall and wind through the evergreens..
Being in my bed or thinking about fond memories or places. I've recently been thinking about my elementary schools library and how it used to smell so nice and I would really love to come back. I don't think I've ever felt safer than in that library.
Cuddling up with a blanket fresh out of the dryer is max cozy. Bonus cozy points if the blanket is shared with someone else (e.g.: significant other, a pet).
might be biased by the current weather state but definitely just curling up in a blanket, hot drink in one hand, kindle in the other... absolutely perfect. or really any combination involving being warm and snuggled up inside doing something relaxing while the weather is anything but inviting!
