Put a black or dark grey sheet of paper in a picture frame. The paper must be on the glass of the frame.
That's the only way the picture looks like a real school board.
Afterwards, the "panel" writes or paints according to your own ideas and ideas with wishes, the name of the school child or with utensils from everyday school life.
Bright colored crayons shine on the black paper.
The table is suitable as a gift or as a display for the breakfast table.
Stay creative!
If you use table foil then you can describe the "panel" again and again and wipe away again.
