Edgings are fun--you can make a design by taking a flat piece of something (towel?) or you can dress up a plain knit or crochet design with an edging. (One gift I was given is a regular old hand towel with a crocheted top and loop, and some decorative edging. It is the HANDIEST thing for the bath, kitchen or garden to wipe hands. If you like to crochet and give gifts, these are fun to make and great to give as a houseguest gift.)
This book has edgings in crochet, along with large photos and clear diagrams. UNLIKE many edging books (and there are MANY), this book is useful for the way it's presented. There may not be so many edgings, and they may be some you've seen before (half rounds, shells, etc) but the photos are so large and clear, and the diagrams so easy to read that it makes crocheting a breeze. There are WRITTEN instructions below, for those of you who do not like charts.
There were a few unusual edgings I particularly liked--several interesting fringes including a fan-like Dandelion Fringe (fringe emanating from a flower center on the band), an undulating fringe and a tassel-like fringe. I also liked a simple cable band that had a sideways ribbed cable; this would be a wonderful way to add cable insertions to a crocheted vest.
There are many things you can do with these edgings. Even though you may have an edging book, I recommend this one for the new edgings and the beautiful, clean pages with easy-to-read instructions. Very nice book.
