The Neverending Afghan

As you know, I'm trying to finish my sister's Christmas afghan before starting on other holiday projects. The afghan is almost done. I have most of the rows sewed together. I knew I had to make seven Magenta squares to finish the last two rows. So I made those and commenced sewing those rows together. To my surprise, when I came to the last row, I discovered that I was short two Windsor Blue squares. Alas, this afghan is never-ending!
