I built the #332 Morris Chair from the plans in this book and found a huge mistake in the measurements: the chair was fully 4" too wide (I caught this in time to fix it, thank goodness). In Mr. Lang's drawings the seat area is measured at 27" wide; in all the Stickley catalogs, it's clearly labeled as 23". Several of the other dimensions were also questionable.
Much of the information in the book, in the text and the drawings, is very valuable. I've enjoyed the book and would buy it again in a minute. Just make sure, if accuracy is important to you, to check his details against every picture and description of an original piece that you can find!!

This book is an excellent compendium of arts and craft style furniture, but boys and girls, check your measurements when you start some of the pieces. I built the wardrobe No112 and have pretty good shop experience. I found errors all over that particular wardrobe. I can understand bad measurements but some were obviously the planners fault.
Admittedly I have not built anything else in the book and this is a fairly elaborate piece. But I found myself shaving off full half inches where I shouldn't have to. Triple check any measurements made and you will be fine! It is unfortunate that such a detailed book with great ideas for plans does not have its measurements doubled checked. The scales for the furniture in the book do not match some of the drawings either. When I get a series of drawings I expect the measurements to be tried and tested. The book does have a good set of suggestions to build the furniture. Sometimes drawings are missing though that would clarify the project. The economy of pages makes the carpenter lose out.
