Keep chaining multiples of 3 until you are happy with the length.  If you just want to practice this stitch, then try making a chain of 12. This will allow you to create a sample swatch. For a larger item, such as a washcloth, scarf, or blanket, make chains in multiples of 3 until the chain is the length that you want the finished project to be. across the chain. To complete your foundation row, you will need to double crochet into each of the chains in your first row. Start with the third chain from the hook and double crochet to the end. To double crochet, yarn over the hook, then insert the hook into both of the top loops in the next stitch. Yarn over again and pull through 1 loop. Then, yarn over again and pull through 2 loops. Then, yarn over again and pull through the last 2 loops. After you reach the end of the chain, turn your work and then chain 3 to begin the next row. This chain of 3 will provide slack to continue working your project.
