Back to School

Amazing what I can get done when I have a couple days off and nothing on the needles.  Last night I pieced the last two block rows for Washington Medallion.  Notice anything a little "off" on the last row?

Apparently I need to go back to school to learn to count.  Guess I should have re-checked when I thought I ended up with an "extra" block.

I still have to sew the setting triangles on the block, but the row has been ripped apart where I want to add the "extra" block.
