The C blocks took a really, really long time to get through. Between selling a house, having two birthdays in the family, and a round of tests and subsequent grading at work, it just seemed like they were never going to end! The D blocks (squares) were a lot easier to plow through in a spare moment.
I am going to switch back to my spring quilt to make the pointy E blocks. That one is only twin-sized, so it is always goes much faster.
