Friend Marilyn to the rescue! I had all of the shapes drawn in pencil on the wall and would have proceeded to draw on quilt designs - actually I did for one of the squares. But she suggested I paint them all white so the colors I use will be true. But of course! I would have ended up doing this the hard way because I overthunk it.
This is a busy week coming up so I don't think I'll get to this again till next week. The white paint will cure and I can then do some sketching and maybe even do one of the squares!
