First glue 3x two craft blocks together on the narrow sides with VBS handicraft glue together to create three individual long blocks. Now lay one of the glued blocks flat on the surface. Now glue the other two upright at the front and back of the long sides to create a U-shape.
Now glue the candle holders into the space in between.
Extend the built kandelaar with more blocks so that you have a small base for miniatures.
Paint the small wooden train set with VBS craft paints and allow the paint to dry.
Arrange the miniature fir trees, moose and wooden train set on the base and fix everything in place with some handicraft glue.
Place adhesive wax plates in the candle holders and place the stick candles inside.
