What a lovely and original Advent calendar from French designer, Zü. She has very generously shared the printable forms so that you can download and create this free advent calendar yourself. All you need is a printer, some paper and scissors and string. Instructions in French and English here, with of course, the printables.
Zü also has an online shop with her lovely creations such as vintage cloud cushions, sweet raindrops below and wonderful vintage posters. Take a look here.
