I am still waiting for the green fabric to arrive so I have not done anything with that clue. I did cut and make the pinwheel units and extra unsewn triangles today. I only cut enough for the pinwheels and 4 extra but not enough for the remainder of the 41 sets.
I think I will need to re-read some of the clues. I don’t remember leaving any other units unsewn before. Maybe that was the clue using the green? Hope I have not messed up on sewing when I shouldn’t have.
