Unfortunately, I forgot to take a picture of the blank box. So just imagine it here.
Here was the next step. I got really lucky and found out my square punch fit the drawers almost exactly! It made it a breeze. Even without, you could use a paper cutter to easily cut out 25 squares. I used an old collection of Basic Grey paper I had, Blitzen collection, and one page of the Dasher collection. Then I used my circle punch to cut out a little spot on each square. I wasn't too picky about placement, as you can see! But I did the whole thing on December 1st, so I didn't stress about making it perfect. I inked the edges of each piece of paper with red ink from an Around the Block inkpad.
After I had that step done, which took several hours, I started to do the numbers and embellishments. I mod-podged everything on. I am not very creative, so at this point I went to Pinterest to find something inspiring. I found the toolbox calendar on this post helpful. I used her method of getting numbers from any source possible. I have tons of letter stickers, so I used number stickers off some of those sheets. I also used chipboard, some little tags I had from getting my car serviced (I never throw anything away, and once in a blue moon, that is a benefit!), cutout from Making Memories paper and 7 gypsies bingo card paper, an ATC from Paper Studios, Smashpads calendar tape, and 7 gypsies ephemera for the numbers. 
Then I added embellishments. Again, I used a lot of stuff I've had for a long time. I didn't buy anything for this project except the box, which was great. I have a big bag of Christmas stuff, and it was nice to use some of it up, and a nice challenge, too. I'm not even sure where some of them came from. But some embellishments I used are:
word strips from Making Memories (Day 2, 24), We R Memory Keepers washi tape (6, 11), Spare Parts acrylic sticker (Day 20), Love Elsie (22). Other: stickers, 3-D stickers, ribbon, bakers twine, tags, punchout snowflakes, copper word accent
The last thing I did was fill the drawers. It was so fun putting it all together. I put little candies in some of the drawers (See's Candy, our favorite), a few pairs of Christmas socks, some little presents like Lego mini figures, and a bunch of paper strips with tasks on them, like donate old toys to charity, sing carols with the family, take Christmas photos, visit Santa, etc.
