Okay it really isn't a square it is a Hexagon. Well, I know how to make a hexagon, but just in case you don't I've included the site where I got the pattern from. Now this site has lots of things going for it, Debi has lots patterns on this site and lots of other stuff you'd want to see also.
So take a few minutes out of your day and spend a few of them looking here. Now I will post the photo of the way I made mine and the colors I chose. I didn't have the exact colors I wanted to use, so I just chose the best I had.
