When I purchased this product, I thought I was getting a good deal because of the cheaper price. However, once I received it, I knew I had made a mistake. I've been using this product for several years now, and I knew just by looking at this one that it wasn't right. The texture was incredibly thin, and the color was much lighter -- something that could only leave me to believe that maybe water had been added to it.Lesson learned -- spend the extra money -- you're paying for quality!

Ex Output:
Negative

This book, published in 1996 and half of which is a directory of shops, was bound to be outdated months after publication much less ten years after, as it is now. Hence the four stars instead of five.Given that, the first part of the book is crammed with a precis or summary of Flusser's recommendations that he has used several hundred pages to expound in his other books ('Clothes And The Man', 'Dressing The Man') and makes the book worth the (used) book price.I do not understand others who warn against this book because they think it is not objective enough! This is a book written by Flusser so of course you will get his subjective view. Had it been written by a committee of tailors, well then, I would expect a more balanced view, but it is not. It is up to the intelligent reader to understand they are getting a product of one man's opinion and then proceed accordingly.

Positive


Ex Input:
Dollar store quality. Lovely dark pattern, but it is printed on thin white flannel, not over-printed on blue yarn-dyed fabric, and the stitching on these fairly dark sheets is white.
