Bédu : "Je peux passer des heures sur une seule case"

• I would like to know how big are your sheets of paper... If I see the pictures here, I think you draw on A4, is that correct ? So for 1 page, you make then 2 x a4 ?
  And I would also like to know then how "high" are your "pictures".
  Thank you for your answer and keep up the good work. Jakob.
