The tiny 9 patches finish at 1.5 inches!!! Each square in that 9 patch finishes at 1/2 inch. The full size 9 patch and the coordinating shoo-fly bocks finish at 4.5 inches. There are 221 main blocks. The quilt will finish at around 75 x 85 inches depending on border choices. I am leaning towards the suggestion of piano keys.
