Alright, so you've finally mastered the single and double crochet and you can increase/decrease, now it's time for the square to look a little fancier and more intricate. As you can see, this one does have holes, but still many uses. I've actually made a bag out of granny squares and a lot of people make afghans out of them. This is about the simplest one out there. You start in the center with a loop and work circularly around, making corners as you go so it ends up being a square.
