Beth from New York teaches how to make a basic half double crochet. You will need: Yarn and hook. Look carefully at your job, and make sure that you see the hole where you should insert your hook clearly. Yarn over once, then insert your hook to the hole you already seen before with two threads above your hook and one thread below it, yarn over again and draw the loop pass the hole. You will have three loops on your hook by now. Yarn over, draw the thread pass through all three loops, and repeat it as much as you like. Follow Beth's half double crochet instructions and make your own scarf now.
