This DIY advent calendar garland has a definitively celebratory feel to it, which is perfect if you celebrate Christmas as the birthday of Jesus Christ. From the SNUG.STUDIO blog, the homemade bunting doubles as a holiday countdown.
The simple craft is made with twine and differently colored bits of triangular paper. You then affix numbers 1 through 24 (representing the days leading up to Christmas Day) in a random order. You can either write a nice message or explain what corresponds with that particular day. This could be easily used to create instructions for a festive scavenger hunt or something similarly creative. In a like vein, you could go with a blue color scheme or customize it to make it your own.
