Natural advent calendar by Török-Bognár Renáta . gun to do together at a certain time everyday.or every person gets an item to add to the Christmas picture in their post.baby Jesus last.donkey, sheep, etc.
I have two variants of this. The 'things from nature' basket which just has shells, wood, stones, feathers etc and 'natural objects' basket including many items from here. This was an easy place to start.
