I decided to keep the quilting simple, so I used a close-set almost-straight line quilting design, nothing elaborate.
This was a fun project to do, it made me s-t-r-e-t-c-h in a whole new direction! I had a number of solids in my stash, but I never deliberately set out to make them the main part of a project - a solid was just a no-never-mind part of my stash.
I was a little brain-fazzled when I started out because I honestly had no idea how to approach this project. But... it was after I realized I was to use the painting as an inspiration that my mind turned down another track. What a wild ride; thanks V for the challenge!
Edited 7/11 to add more info:
I made my hanging sleeve according to these instructions on the Alzheimers site, the first one.
