You guessed it, it's Rumi of Fashiontoast! I love the effect of drawing on brown card, it makes the drawing seem more interesting and almost vintagey. I buy a lot of things from Amazon, and I've been a bit of a magpie in saving the packaging. But now I can use them to build my own sketchbook; I'd love to do more drawings in this style and eventually tie all the images together and make a front cover. Try it out yourself!
