THIS NEEDS TO BE A PAPER PIECED PROJECT! OMG! Why would he do all this work and try and keep the measurements exact, when if paper pieced...you are right on the line. You can see how some of the block are off, pieces not meeting from block to block on his project. Beautiful pattern in this quilt. I would do it, but only after I ran piecing paper through my printer. So much faster and lot more accurate.
