Review on 🌈 Rainbow Scratch & Sketch Art Paper (16"x 11.2") for Kids & Adults - Night View Paris Scratchboard Painting Kit with Scratch Cards, Drawing Pen Stick, and Clean Brush - Perfect Painting Gift and Art Craft Activity for All Ages by Sasha Hsiao

I suggest making one of those scratch and sketch art projects where you don't mind the mess. When the matte finish (the areas that show up in blue or gray depending on the project) is removed, you'll have little bits all over it. You will receive a drawing board of your chosen cityscape and some tools (brush, wooden stick, pen). Gradually scratching the surface reveals a colorful array. This is very smart but requires patience as it is time consuming. It could be something you work on and come back to from time to time, like a big jigsaw puzzle.
