Okay I have to admit that this was not my idea. I have seen these several places on the web. Recently I received a few email requesting a pattern for the Book Thumb. I could not find anyone who claimed it was their original design. If you know where this idea originated let me know and I'll give them credit. I will also remove this pattern if requested by the original designer.
I included two different sizes of thumb holes. You may also want to experiment with the length to get the feel you want.
