The entire chapter of The Tale of the Three Brothers from Harry Potter and the Deathly Hallows on the wall, word for word, by hand. I don't know if i would do a harry potter chapter, but maybe another book chapter!
Maybe in the office, art studio or the used book/game/comic store This a cool idea for art work in a space. If it is a temporary space for you, cover walls with white butcher paper, then go to town drawing.
Stair art hand painted on MDF and then installed. Much easier (and less permanent) than painting directly on the stair risers! By Michelle Allen this would be awesome on a staircase leading to my craft room!
