I found an advent calendar kit from years ago and decided to decorate it for my granddaughter. I assembled all the pieces and painted them red. Painted the numbers gold. Added a decorative striped paper to the drawers before adhering on the numbers. Adhered a large scrapbook paper to the center and added some rub-ons.
I thought it would be fun to replace the drawers backwards into the calendar after each one has been opened, so I added 3D Christmas stickers to the back of each drawer.
