I purchased this book, sight unseen, based on the glowing reviews given here. I'm very disappointed and would send the book back if the hassle of doing so wasn't greater than the cost of the book.
I have the very first Harmony book of crochet stitches, which is decades old... the one put out before they started numbering them and telling you how many stitches they contain. I thought this book was a sequel to that original one, but it is not.
It appears that they simply tore apart the original book and made it into two seperate books. This one, vol. 7, contains very few stitches that are not in the original. For instance, in the first section "All over Patterns" there are only 18 stitches that are solid fabrics suitable for clothing (versus openwork, filet, edges or motif patterns) and only two of those are new to this book. If you're new to crochet and want open work stitches this book would be great. But if you've been around awhile or want stitches that make solid fabrics suitable for clothing or warm afghans, skip this book.
