Using Lauren Espy's books is super easy. Just pick a pattern you like from the book. You can start crocheting right away if you're familiar with basic crochet stitches. For beginners, it might take a bit of practice to get the hang of it. As you work on your project, pay attention to the stitch counts and any special instructions in the pattern. When it comes to materials, use high - quality yarn and appropriate crochet hooks. After you finish your amigurumi piece, you can gently wash it by hand in lukewarm water with mild detergent. Let it air - dry flat to keep its shape. Store your finished items in a cool, dry place to prevent damage.
