『Beautiful crochet book』
Usually, when you want to crochet an item using little round or square motives, you will have to crochet one, break the yarn, hide ends, crochet second one, break the yarn, hide the ends, and so forth many many times.
This book teaches you how to crochet the same regular motives but without breaking yarn and hiding zillions of ends. There is a step by step guide how to do it, and then a whole lot of motives with schematics on how to make up a fabric from them. There is a few projects at the end of the book using the patterns presented to get you started with your crocheting. Very useful book!
