There are so many nice ideas on the internet for advent calendar that I had to create my "own" :) I created some small bags from paper and put some chocolate and typical xmas surprise in it. I decorated a desk at the office and put the bags on it. Every day someone's name was chosen and that person could take the bag for the given day. On the bags we put some numbers to indicate the date. I think it's very easy to create this type of present and people were fond of it.
