Lets see, multiple lights for the background, greens, brown, red, are secondary and then other red, coral, black, gold, for pops of color. You only have 4"x wof of black. You might could get 40 to 42, 2" squares of black. That could be sashing squares or centers of something like a 9 patch or log cabin. Quite the puzzle you have there! I would have fun cutting into that and coming up with something. Nice find!
