There are plenty of possibilities to make a reusable advent calendar. Here is one idea for a minimalistic calendar which can be used years after years, and which looks decorative also when all the pouches have been emptied.
You just need some burlap, felt fabric and band. Use a heart shaped Christmas cookie cutter as a pattern.
This calendar had been in use every Yule since the early 1990’s. The pouches are not filled yet in the photo above.
All the pouches are filled! December may come!
