Kristina loves hanging white Christmas lights everywhere - our living room during Christmas, our porch, etc haha. Normally, I am of the opinion that they are tacky and that they only belong on a Christmas tree, but recently I have seen a lot of pictures of the twinkling lights looking very cute. I think that the space you have the lights in has to be appropriate, and that is where most people go wrong and end up making their apartment look like a cheap college dorm. Maybe I am reconsidering them!
These are fun:

oh, hello friend.
I like the way these are casually draped in a non-tacky way:

Still cute in a fancy apartment:

Icicle lights behind a headboard for a lovely glow:

So, Kristina, if you can figure out a way to make our apartment look cool like this, then we can hang the lights up again this year! :)
