My good friend Robin Brenner is an expert on graphic novels (she's a former Eisner Awards judge) and the young-adult librarian at the Brookline, Massachusetts, public library. She's also very clever with her hands, as you can see from these book hedgehogs she made from discarded books.
The basic algorithm for making book hedgehogs is pretty simple, but Robin took it a step further and came up with a whole array of personalized hedgehogs based on comics characters. Here are some close-ups, including the tiny bow and arrows for the Hawkeye hedgehog, and here is a gallery of more characters. It's amazing what you can do with an old book, some duct tape, and plenty of imagination!
