If you have made this or are intending to make this (in which case you had better get cracking) and are needing some ideas of what to put inside I am sharing this post to let you know what I am doing (which you can copy exactly if you like, or you can use it as an idea source and modify it to suit your family). I have included a printable calender so you can remember what it is you agreed to do each day and put it in with your other plans as well as 3 sets of tags to write the activities on and then fold them to put them in the boxes. Not every day will need a tag. Happy creepy crafting and counting down.
