Every time I draw one of these cottages it takes me back to my childhood, reading Grimm Fairy Tales. Those were my favorites The ones that were really grim were the ones by Hans Christian Anderson. They used to scare me to death. He was Stephen King for children. One title I still remember: The Girl Who Trod on a Loaf. Terrifying.
The brothers Grimm had some scary ones too, but fortunately my book had such winners as Cinderella and Rapunzel. There's nothing wrong with a happy ending.
