Literally, of course, that's a bit of a theme for me in the winter. I HATE being cold. So, I buy electric mattress pads and I knit (a verb for keeping warm, as Jill says), and I buy horrifyingly expensive new windows for my house to eliminate (some of the) drafts.
Yet, really, I'm talking about metaphorical warmth. I'm trying to figure out what makes my house a warm home. What makes me smile about it? What comforts and soothes? Candles. They have a "company's coming - you're special" vibe that calms. Music in the background -or the foreground, as the case may be- is essential. My mom leaves the stereo on even when she's not home, to make sure there's a little noise in the house when she walks in. I don't do that, but I get the idea. Solitude can be good, in reasonable doses. But too much silence has a pressure and a heaviness about it. It's not good for people like us, apparently. Books are important. I curled up last night with a book -a book I was reading for pleasure, which felt unbelievably decadent- and was truly happy.
I need a better bathroom -candles, cozy rugs, bubbles, music, the whole girly thing. My bedroom still needs a smidge of warming up, although it's better than it was when I moved in. (And yes, I bought the remaining curtains!!!) At least one guest room needs to be ready and inviting, which right now it emphatically isn't. It's a bit more like Santa's workshop at the moment :( I had a party and we plowed through my modest wine collection (which was all of 4 bottles, but still....), so that needs to be started over.
But whatever I do, I think I have to ask the question "does it add warmth, or light, or welcome?" If I can't make the argument (to myself... and really, I'm not a tough audience.) then perhaps it's not the right thing for me to be doing.
