Winter Wedding Invitations

Many people plan their weddings in the summer so that they're not uncomfortable or cold in their wedding garments. No matter what time of year you get married though, you're not assured that you'll have good weather on the day. 
I was a winter bride, but funnily enough, the sun shone in all its glory for two hours that day. It was all the time I needed for the outdoor bits, thankfully. We didn't have a glorious, massive wedding, so the need for wedding invitations did not arise.

If you're planning your winter wedding would you go for winter wedding invitations with snowflakes, robins and other seasonal tributes, or would you choose a more general sort of invitation?
For me, a summer wedding seems to be much better than one held in the colder months, but if I was going to go for winter renewal of vows, I think I'd have to go all the way and have all my invitations, food, centre pieces etc, fully winter themed.
