Hanna Karlzon is an Umea, Sweden-based illustrator and creator of the best-selling coloring books, Dagdrommar and Sommarnatt, previously published in Sweden. She creates elaborately detailed images using India ink to detail pictures from her own imagination and loves to draw flowers, forests, houses, and animals. She draws her inspiration from the natural world that surrounds her studio in northern Sweden and adds in some art nouveau, punk rock, and often a hint of '70s design to the mix.
