Finished it just in time!
I went on a search for an advent calendar tutorial without pockets. I wanted something different than the norm, something that I wouldn't have to think hard about what to put in pockets. I'm too lazy for that (and cheap).
I came across Wee Folk Art's Advent Tree tutorial and went for it. I liked the hand sewing aspect, which allowed me to stay warm by the fireplace while working on it. I also was able to use up a good bit of a box of 1" buttons I'd bought a while ago that I never used.
You might not be able to tell from the picture, but the star has a button hole, and it starts at the bottom. Each day, a lucky kid (in our case) gets to move it up to the next number. They are already stoked to begin. :)
