In this how to video, you will learn how to do a tornado stitch. This stitch is similar to a quad stitch. However, instead of bringing the strands straight across, you bring them across diagonally. First, bring the purple strand up and to the left and bring the top purple strand down and to the right. Apply this to the yellow strands. Once this is done, bring the left orange strand right and upwards. Bring the right orange strand left and down. Go over and under and repeat. Do the same with the black strand. Once this is done, pull on all the strands to tighten the stitch. Repeat this entire process until you are ready for the finishing stitch.
