How do you spice up your profile with a christmas theme?

I'm currently using this background: https://steamcommunity.com/market/listings/753/267420-Holiday%20Sale%202013%20-%20Sasquatch, probably going to add some xmas themed emoticons into my description box as well.

You can purchase themes from the market or trade them with friends (if they have any spare)
http://steamcommunity.com/market/

If you just want to see them for yourself install enhanced steam and you can use any theme for free. Only works in the browser and only other enhanced steam users can see it.
