I finished my 3 squares of Parisian stitch.  The first one came out pretty good:

I turned it a quarter-turn to work and spent a lot of time pulling each thread in the 3-thread strand after making each stitch so the threads would lay flat and even.

My second square is my own design based on various samples I saw:

I really like how this one came out.  I centered it exactly and had to do fill-in stitches on each edge.  I think it came out great.

My third square is a copy of one of the samples in the book done in my own colors:

This is George's favorite.  I like it too.  I finished the square and then noticed that I had mixed up  some of the colors on stitches in the ribbon so I had to cut it out and re-do in the correct colors for the pattern.  The front looks great, but I won't be showing off the back of this square to anyone.

I now have 8 of the 25 squares filled in and have to start paying closer attention to the overall appearance of the sampler.   I also need to decide how I'm going to fill in the lines between the squares - one color, multiple colors in patterns, etc.
