Puzzle Piece, Progress #4

I have been working on my Puzzle Piece, hoping to get it finished before the end of the year.  I don't think I'm going to make it, but I'm still trying.
I didn't work on it for several months and just got it out again a few weeks ago.  It is a fun project, but it does require me to make constant decisions about stitch placement, color & thread.  Sometimes I just don't have the energy for all that!
I have two bags of threads for this project - one has the threads I've used so far and the other has possibles.  More & more threads are migrating to the "used" bag!  I can't believe how many different threads I've used so far.
