Here are the steps to finish a stitch:
1. Once you have reached the end of your line of necessary stitches, knot the thread again by pushing the needle part-way through the wrong side of the fabric and then back up through the right side of the fabric so that the needle both enters and exits the cloth on the wrong side of the fabric.
2. To finish off and knot the thread, wind it around your finger and then pass it through the loop you created. Pull it tight to create a knot.
