Hi Omar! Curious as to what kind of materials you use for your sketches?Thank you and have a lovely day :)Anum
I use a travel set from watercolors from Cotman (Windsor and Newton), a squirrel brush from Da Vinci, Sepia color Faber Castell Pitt Pen (they are water resistent) My Sketchbook is from Stillman and Birn, 150 gsm paper white . The quality of the papaer is very important. There are not many good sketchbooks where you can use watercoors.
