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.
