Ok, here are some more......

First I want to say thank you for all of the comments and insights into the choice of my alternate squares.  They were eye openers that showed me what I didn't see.  However, those who suggested solid colors, well that just isn't me.  As far as the blocks being beautiful, I thought they were pretty boring and hoped that an alternate fabric would spice them up.  So you see, we all see something different.  Here are 5 more fabrics that I tried, and I know I probably still haven't found the right one yet.

Sorry about the shadow on the last one.  While I had the black and white fabrics out I had to try a blend of values with them to see if I had enough pieces with large enough yardage to do a Trip Around the World with them.

One photo has the lights in the center and the other the darks in the center.  I like to view it both ways to see if the blend is good.
