I have one wall in my living room that displays my cards. It is the first wall facing you when you walk into my house so I use it to create my "masterpiece".
I recevied so many compliments last year on my "wall of cards", that I couldnt wait to do it again this year. My son counted them last night and there are 18 up there so far.

I think that I had around 50 last year.
Its one of those happy things that you cant help smiling when you look at it because you know they are all from friends and family.
