It's stitched on 14 count white Aida, and finished the stitching measures out to about 11.5" x 11.5" (though the design specs say 12"x12"). There were 19 colors total. I can't count the hours I've spent on it, as I believe I worked on it in three big chunks: when I first got it, finals one semester, and now.
But onto pictures!

And the back! Not as neat as some of mine, but neater than others.
