Four Patch Posie Plus Number Six Does Not Equal Ten

Busy day sewing Four Patch Posie sashing with cornerstones... more of the same from the earlier post, but I'm ready to assemble the quilt on Saturday.  I also completed the pillows and a Farmer's Wife Quilt-A-Long block (#6).  I have to admit the first block was so bad I redid it twice.  I was trying a trick to sew the triangles fast, but started with strips that were too small to begin with.  How annoying.
