I am very surprised at myself. This block has 47 pieces, none of which is larger than 1/4″ (0.6 cm) and I still would not say that it was very difficult. It was not easy, but the difficulty resulted from the small size of the pieces rather than the complexity of construction.
I broke the block down into seven paper pieced sections; once I had completed the sections, I sewed them together and voila!
This is block # 138
