Heya! (Hehe, and not a bother at all!)
When it comes to actual sketchbooks, I usually have Strathmore branded ones! (The type of Strathmore book can vary, as it depends on what media you’d like to use on those pages! But the ‘Mixed Media’ is usually the best route to go if you’re like me and you like to use pen, colored pencils, and even paint on your doodles sometimes, without worrying about any smudges!)
But any other time, I’m just as likely to draw on regular sheets of printer paper, cardboard; pretty much any free ‘canvas’! :D
(And gosh, thank you so much, hehe! Insanely flattering! <3)
