A2 format
   Materials: pencils USLON H, HB, B, 2B, 3B, 4B; Eraser Faber-Castell, drawing paper, klyachka or formoplast as needed (I did not use it, but it can be useful).
   Advice: it is better to pull half of a sheet of drawing paper on a tablet so that the paper does not give waves and is tight and evenly fixed
