RRCB....Still a mystery

Step #4 of Bonnie Hunter's mystery "Roll, Roll, Cotton Boll" was quick & easy, resulting in these little green and neutral units.



On the other hand, Step #3 (the neutral string-pieced blocks shown below) took hours & hours. The 60 blocks consumed lots of scraps, and I had fun making them all! Some of the fabrics make me smile...I've even got a treadle machine in there.

These are all the completed steps shown together, with the blue "constant" underneath it all. This mystery remains a mystery. I just can't imagine how all these blocks will go together!

Step #5 is expected on Friday.....I'm looking forward to the next clue.............
