The author, Carol Vincent, studied at the Royal College of Art in England and so is an expert in this subject. This smallish 128-page book is filled with motifs in the following chapters: Buildings, Figures, Trees, Animals, Border Patterns and Floral Arrangements. The majority of graphs and photos are in color which is nice. I like the discussion at the beginning of each chapter to give the historic perspective of the meaning of the motifs.
I quibble with only providing 16 different alphabets and only one blank page of a graph for designing. I would also have greatly appreciated photos, even in black and white, of historic samplers to get a handle how to incorporate all the individual elements into one sampler. How do I determine placement of the motifs and border, at least one alphabet, and probably a poem or at least "wrought this day by ____"? I have dozens of books on historic samplers (including titles in the bibliography) so I have extra resources here, but if this is your only book to design your own sampler, you'll have to rely on your imagination quite a bit for your overall project. If you're confident to design your own contemporary sampler anyway, this won't be a problem; I guess I prefer a little more direction, even though I've stitched several samplers.
For its specific purpose of being a workbook, despite the statements above, it is a happy little book that inspires stitching which, after all, is what we're all about, right?
