Hey ho,
So far, the elves had to eat from the ground, that should change today. For the decoration in front of the Wichtelhaus, I imagine what it looks like when new furniture comes. For example, you can make a furniture packaging from cardboard and draw a small instructions. If you can find tools in the children's room (Lego or Playmobil), you can also decorate it.
As the parts belong together, I do not need to explain to you, here too you can't go wrong.
Have fun having a happy handicrafts.
