Adinkra is a type of cloth worn in Western Africa. It is a printed grid pattern made up of combed grid lines and a small shape printed in the squares.
You will need:
Wide toothed comb
To make the grid, dip the comb deep in the paint so that most of the length of the teeth are covered. Drag the comb along the paper, turning the comb over and adding more paint when needed until you have drawn a grid pattern.
Cut the potato in half and cut out a design from one side. Dip your potato in the paint and stamp the design in the centre of your grid.
