The creator/artist is Marilyn Scott-Waters. I bet if we were to look inside her head it would be a kind of Wonderland in there, so creative! She also offers a Toy Maker book on Amazon and has illustrated a book, The Search for Vile Things, that I've already added to my Amazon wish list!
My favorite paper toy is the Tooth Fairy Gazebo!!
