Now that we've covered the basic slip knot and chain, it's time to move on to the very simple slip stitch. In pattern instructions, this can be noted as "sl st".
I don't think I mentioned this, nor was it covered in the tutorial, but some may be wondering what the best way to hold the thread and finished when crocheting. For right handers, it works best to hold the chain, (or finished work, when you're far enough to have something to hold onto), between the thumb and first and/or second fingers, or even the whole hand, while threading the yarn or thread through the rest of the fingers on the left hand. It will be the opposite for lefties. With time and practice, everyone will find what is the most comfortable for them, and what works the best. Whatever works for you should be relaxing, not tense and awkward. Remember, this is supposed to be relaxing!
Also, the more you work, the more you'll find the proper tension when it comes to holding your yarn. "Tension" is how much and how hard the thread is pulled as the crochet stitches are being formed, and how tight the stitches will be when finished. If pulled too tight, the stitches will be more tightly formed, and the opposite when less tension is used.
With that said, here's the tutorial on creating the slip stitch. Have fun!
