This is the book I turn to when I am looking for an interesting embroidery stitch.
Sue's book Creative Stitching includes step by step concise written instructions, along with clear illustrations, for 50 wonderful stitches. Included are close up, color, photographic examples of each of the stitches used. Creative Stitching is spiral bound to stay open to the page you are using. It is a handy size to carry with your stitching. It has an alphabetical index in the back of the book along with a category breakdown of stitches in the front which allows you to choose a stitch by the effect you are looking for.
