Did this quilt myself a couple of years ago. My LQS was offering a pp'ing class and this was it. The class was only 1 day so manageable from a schedule standpoint. I thought it was a great exercise to learn paper piecing as it was so repetitive. Unfortunately for me, this completed top has been sitting in my UFO pile because I can't figure out how I want to quilt it. I'm a hand quilter and all those seams are a tad intimidating.
Yours is lovely and I don't see any 'pointy arcs' at all! Great job.
