Paragraph 157. This stitch consists of a loop of yarn or thread drawn through a chain stitch forming two loops on the hook through which another loop is drawn. To do this, make the chain as long as desired, then crocheting back over the chain, insert the point of the hook through the next loop in the chain; draw a loop of loose yarn through this chain stitch, thus forming two loops on the hook. Catch the hook in the loose strand of yarn again, as in Figure 68, and draw another loop through the two loops on the hook, forming a new loop to begin the next double crochet. Continue as far as desired. The abbreviation for double crochet is d. c. This stitch is used in a great many kinds of crochet.
