A very pretty one from Etsy with clean, modern images. Notice the numbers are in sequence - no hunting. This one would also work well as a sensory bin - with 24 tiny presents, and maybe even 24 tiny box lids to act as trays.
Advent calendar This holiday calendar center a lot on family activities. Instead of gifts and goodies, printed little cards for the advent pockets. Would be an awesome idea to get ready for Christmas:)
