I own three of the Miss Bea books and like them all (even though there is some repetition each is unique) but this is probably my favorite. The patterns are very practical for children but each with a little twist to make them unique. Patterns are simple to follow and knit up quickly. I just finished the hearts sweater and started on the umbrella sweater. The diagrams for the patterns, the finished measurements, the color coding, the book layout are all great -- what more could you want. BTW, I did use a different yarn of same gauge and it worked fine.
Only reservation -- You may want to check the measurements first as they do seem a little on the larger side.
