As I was refilling this Christmas Countdown Advent Calendar that I did a few years ago, I decided to post
it here for any that hasn't seen it. Made with a cookie sheet from the dollar store, the little 3D cardstock Trees hold little surprises for each day of the Christmas countdown. Spakling pipecleaners hold the textured trees together. A small magnetic on the back of each lets it stick to the board and makes for firm hold, but easy removal. It hangs from ribbon which is attached to sticky picture hooks adhered to the back.
