I feel your pain on this one. When I first started quilting (self taught) less than 10 years ago, my daughter picked out a beautiful queen sized quilt from a book I had. Each block consisted of 25 pieces if I remember correctly. I wracked my brains because it wasn't going together after the first trimming. The book was misprinted with the measurements for that part. A cable tech actually helped me solve the mystery (his ex was a quilter). Quilt turned out awesome.
