First take two slices of bread. Spread one thickly with jam and the other with cream cheese. Engage willpower and try not to take a bite.....just yet.
Next, cut each slice into three strips. Turn and cut again into three strips. You should end up with 12 white squares and 12 red ones.
Now use your squares to make a chequerboard pattern. Admire your work, pose for the inevitable photo and eat. Yum.
Sorry mum if appetites were spoiled!
