Last Week's CMS/Colloquium knitting

I finished the mitered square part of this knitted object last Thursday afternoon. I have a very small amount left of three of the colors, but certainly not enough to do another row. I'm pretty happy with the size (I did measure it, but I didn't write down the dimensions and now I don't remember what they were).

 My task now is to weave in all of the many many yarn ends on the back. When I first started this back in college, I was very disciplined about weaving the ends in as d finished each mitered square, but since I picked it up again I've only woven in the starting end for each square I which I do as I'm knitting the second row. I've taken this home and I'm trying to do 5 ends every time l sit down to watch TV, so I never feel overwhelmed with this huge and unpleasant task. After the ends are all woven in I'll put a black border on it somehow.
