I cut and fiddled on the design wall trying out everyone's suggestions. I ended up with the blue paisley. I was really trying to make the center glow, but the yellow I had just died - no luminosity in that one. So this is the layout. I have one more row of strings, alternate blocks, and setting triangles, but that would involve standing on a ladder to reach, so you just have to imagine those. Thank you to all that responded with your advice and suggestions!! Now if I can just piece it together without turning blocks the wrong way!
