Package illustration by Melissa Sweet Melissa Sweet (@melissasweetillustrator) is the illustrator of many eeBoo favorites including the Life on Earth Sketchbook and Pencils. Melissa lives in Maine where the natural world is a big part of the landscape and inspires many of her illustrations. Her favorite color is fuchsia and every other shade of pink, too! Melissa loves to go to her local farmer’s markets because her current yard is only big enough for two dogs to run around so her gardening is limited to potted plants.
