Needlepoint - I need a break

I have finished the bottom half of my needlepoint piece.  

 Initially, each square took about 3 hours.  I have improved my stitching technique and now it's only 2 hours.  Times 36 squares...

The top half 

will have to wait.  

 You can see that the yarns have tags on them.  These tags determine their place on the grid.  You can't really see the grid because I only marked one column and have been working off of that.

This is a diagram of the grid to which I attach the corresponding yarn as I work.

 OK, so I need a break, not because I'm not enjoying the stitching (except for neck and back pain for prolonged sitting) but I have other projects to work on.  Next - preparing materials for my fabric book presentation to POM.
