Heads up woodworkers! If you are good at reading technical drawings and need very little in the way of explainations, this is the book for you. If you are either a beginner (alluded to by the word "Simple" in the title) or need detailed instructions, stay away from this one.
I'm a mid-level woodworker and like to make puzzles and games for kids in my shop. I got this book realizing that it wasn't going to be easy just by looking at the project on the cover. Boy was I surprised! There are a few introductory pages at the front and the rest of the book is filled with technical drawings of how to build the puzzles. No detailed instructions or step by step instructions, just drawings and diagrams.
I might delve into it to try to get a pattern or two but this little bitty book (almost more of a pamphlet really) is very intimidating.
