Lay stack of filo sheets on work surface and using a sharp knife, cut stack into two equal strips down its length.
Cut each strip into four equal squares as shown.
You will end up with the stack cut into 8 equal squares.
Keeping all other filo squares covered with cling film to prevent them drying out, lay one square onto work top and brush lightly with melted butter.
Top with a second square, offset to allow corners to show.
Brush lightly with butter.
Repeat with further two squares so all corners are offset.
