[EX Q]: The best thing I found in this book is the picture on the cover. Well, actually the uncropped version in chapter 5. Beyond that, I found everything else to be non-practical from a design perspective. A photo of a filthy dust collector area when discussing the advantages of central collection or electrical wiring that would never pass inspection is typical. I'd rather see plan views of real shops that work with reasons for the decisions made.
[EX A]: Negative

[EX Q]: I was expecting to read a book about the Amish. What I read instead was a very self centered book about a woman searching, rather blindly, I felt, for herself.She had very little in the way of insight into Amish life, even after spending a period of time with them. And her inability to get outside of her own head/her own life was not terribly interesting to read.For someone who always longed to be a 'star,' I am sure publishing a book was quite a thrill for her. Shame she used the Amish as a platform for her own ego.
[EX A]: Negative

[EX Q]: Heard a huge boom and I noticed the seam had given out and then this huge bubble formed in middle of the bed and then it ripped a few days later. I purchased the product on or around 10-6-2011 and before 11-1-11 it was deflated!

Negative
