I love some of the patterns in here! But I've only tested two so far - standard K1 P1 rib, easy peasy, but found the second (Chevron Mosaic on p. 54) to be incorrect! The colors used need to be switched up ( A for B and B for A) after row 16 (I think it is), and neither should rows 1 & 2 be included in the repeats in order to establish the photographed pattern, as I recall. Still happy I got this book, but I don't like that that I now lack confidence in the text's ability to produce the patterns as illustrated. I didn't pay for a stitch dictionary to test patterns. I'm glad I had the foresight to review the pattern and see that it wouldn't work as written.
