Give it a try
Coffee painting is an extremely easy and enjoyable process of expressing your creativity on paper. This type of art may be monochromatic, which involves working with only one colour, but its potential for art is limitless.
To do coffee painting, you will need black instant coffee, water in plastic cups, watercolour paper, a flat paintbrush and a round tip brush.
Lastly, you’ll need a pencil to make a sketch of your painting. If you want to add more details to your artwork, you can also use black pens or markers.
