First glue 3x two craft blocks together on the narrow sides with VBS craft glue so that three individual long blocks are created. Now lay one of the glued blocks flat on the surface. Now glue the other two on edge at the front and back of the long sides to create a U-shape.
Now glue the candle grommets into the space in between.
Add more blocks to the candle holder so that you have a small base for the miniatures.
Paint the small wooden train with VBS craft paints and let the paint dry.
Arrange the miniature fir trees, elks and the wooden train on the stand and fix everything in place with a little craft glue.
Place the stick candles in the candle sleeves and stick wax plates inside.
