Marcia found a website with a handknit monkey mascot from Knitted Toys by Fiona McTague that sort of resembles Curious George. Check out Kristo's blog to see all the fun her little monkey has. He's a cutie.
I just ordered the book. If you are looking for a pattern to knit Curious George, this might be just what you're searching for. Now I just need to find a pattern for knitting a man in a yellow hat.
