Are you thinking about learning how to crochet? Crocheting appeals to a wide number of people, as most of the materials still remain inexpensive and easy to obtain.
Crochet yarns are by nature very soft. Crocheting is also for common ordinary people who simply enjoy the feeling of accomplishing something with their after-work, idle time. It's always best to choose a yarn of the same weight - worsted, finering, chunky etc.
I have known three housewives who have gone into crocheting, first as a hobby, and then into business, making sweatshirts, shawls and pillowcases in different designs and different colors. Books aren't the only place to find these types of baby blanket patterns. If you start with simple patterns such as blankets or scarves you will find the easiest path to learn to crochet.
As a beginner learning crochet, you will no doubt find a little frustration at times. By searching online you will find everything you need to know about crochet.
