Hi Karen, I bought this kit and plan on documenting all 31 days as well...unless I'm massively burned out by Christmas Day. I haven't gotten all my foundation pages finished yet - but I have some chipboard numbers in my stash that I'm going to substitute throughout so it' doesn't look goofy when days 26-31 are done with them. I think you could also pair up numbers from the Advent pieces to create some of those other 5 numbers (obviously not all of them because there are only two of each number...one in each style). You could also use the stickers for the dates as well. I am very pleased with my purchase of the kit for documenting the entire month.
