The pattern is in the book Transparency Quilts by Ringle & Kerr.
Mine is a bit different - I used squares that I had on hand so they are bigger & where the authors used long skinny strips, I sub-cut them, figuring I could handle shorter pieces better.
All of the fabrics are Japanese Taupes.
I pieced a back that used some of these lights & other lights that I a bit darker than these. The binding will be light.
I'm send it off to be long-armed shortly - with organic straight horizontal lines.
