Dunster - please look at the original quilt and the 3 block solution again. I don't see a seam 'right in the middle of the diamond'. I THINK the original quilt does have a seam joining the kaleidescope-like piece and a triangle, so the 3 block solution works. Maybe I'm just 'seeing' things, though - LOL. My eyes are starting to glaze over after looking at all these pictures!
