Is there anything at home that can be used to make a whiteboard and write with a water-based pen?

Hello, you can choose something relatively smooth, such as iron sheet, and then paint it with white paint. But in order to achieve the best effect, it is recommended to buy a whiteboard, because the paint on it is different, and ordinary paint can't be wiped off after writing, but you can also choose glass, but the glass is too smooth, and the writing water will be scattered and fragile.
