I saw the pattern for this advent calendar a few years ago. I had searched all over for a pattern for a nativity advent...there aren't a lot out there. Growing up we had an advent calendar that we would race each morning to be the one that was able to put the new piece up for the day. Now that my girls are old enough to really get into it I wanted to have one at our house. The pattern that I used for all of the pieces is from Art To Heart.
Then I wanted to change up the manger and background a little bit so we made up this pattern. I love the way that it turned out. It was A LOT of work and time, but it will be a fun addition to Christmas at our house every year!
